Nafion-美国博纯
Nafion®是聚四氟乙烯(Teflon®)和全氟-3,6-二环氧-4-甲基-7-癸烯-硫酸的共聚物。
简单说,是Teflon结构伴有另一氟碳临时侧链。
侧链的终点是一个磺酸基(- SO3H)。
如同大部分的含氟聚合物一样,Nafion具有极强的抗化学侵蚀性(抗腐蚀)。
磺酸基(- SO3H)固定在氟碳基上,不会被移除。
Nafion重要特性如下:耐腐蚀Nafion®是聚四氟乙烯[Teflon®]和全氟-3,6-二环氧-4-甲基-7-癸烯-硫酸的共聚物,象Teflon一样,Nafion®具有极强的抗化学侵蚀特性,所以它能被用于强酸性气体的场合。
快速因为含有磺酸基团,Nafion®具有极强的渗水性。
在此化学结构中,磺酸基最多可以接受13个水份子。
通过磺酸基团,在Nafion®管壁上形成了一个交联的离子通道,水在管壁表面经过磺酸基吸收后,通过离子通道迅速地转移至管壁的另一面,然后蒸发。
选择性与微孔渗透膜是一种相对较慢的扩散过程不同,Nafion®对水份的吸收和转移是非常迅速的水合过程。
这是一个只和水发生的特殊化学反应,其他物质通常不会受到影响。
过程简单—当水份在气相的状态下由管内转移到管外,没有自由能的变化,所以不需要额外的能量来驱动该反应。
反应的驱动力来源于管内和管外的水份浓度差(湿度差)。

This booklet provides advice and examples for a smooth path to protein purification. Protein purification varies from simple one-step precipitation procedures to large scale validated production processes. Often more than one purification step is necessary to reach the desired purity. The key to successful and efficient protein purification is to select the most appropriate techniques, optimise their performance to suit the requirements and combine them in a logical way to maximise yield and minimise the number of steps required.Most purification schemes involve some form of chromatography. As a result chromatography has become an essential tool in every laboratory where protein purification is needed. The availability of different chromatography techniques with different selectivities provides a powerful combination for the purification of any biomolecule.Recombinant DNA developments over the past decade have revolutionised the production of proteins in large quantities. Proteins can even be produced in forms which facilitate their subsequent chromatographic purification. However, this has not removed all challenges. Host contaminants are still present and problems related to solubility, structural integrity and biological activity can still exist. Although there may appear to be a great number of parameters to consider, with a few simple guidelines and application of the Three Phase Purification Strategy the process can be planned and performed simply and easily, with only a basic knowledge of the details of chromatography techniques.78Chapter 1Purification Strategies- a simple approachApply a systematic approach to development of a purification strategy. The first step is to describe the basic scenario for the purification. General considerations answer questions such as: What is the intended use of the product? What kind of starting material is available and how should it be handled? What are the purity issues in relation to the source material and intended use of the final product? What has to be removed? What must be removed completely? What will be the final scale of purification? If there is a need for scale-up, what consequences will this have on the chosen purification techniques? What are the economical constraints and what resources and equipment are available?Most purification protocols require more than one step to achieve the desired level of product purity. This includes any conditioning steps necessary to transfer the product from one technique into conditions suitable to perform the next technique. Each step in the process will cause some loss of product. For example, if a yield of 80% in each step is assumed, this will be reduced to only 20% overall yield after 8 processing steps as shown in Figure 1. Consequently, to reach the targets for yield and purity with the minimum number of steps and the simplest possible design, it is not efficient to add one step to another until purity requirements have been fulfilled. Occasionally when a sample is readily available purity can be achieved by simply adding or repeating steps. However, experience shows that, even for the most challenging applications, high purity and yield can be achieved efficiently in fewer than four well-chosen and optimised purification steps. Techniques should be organised in a logical sequence to avoid the need for conditioning steps and the chromatographic techniques selected appropriately to use as few purification steps as possible.Limit the number of steps in a purification procedure910Fig.1.Yields from multi-step purifications.PreparationThe need to obtain a protein, efficiently, economically and in sufficient purity and quantity, applies to every purification. It is important to set objectives for purity,quantity and maintenance of biological activity and to define the economical and time framework for the work. All information concerning properties of the target protein and contaminants will help during purification development. Some simple experiments to characterise the sample and target molecule are an excellent investment. Development of fast and reliable analytical assays is essential to follow the progress of the purification and assess its effectiveness. Sample preparation and extraction procedures should be developed prior to the first chromatographic purification step.With background information, assays and sample preparation procedures in place the Three Phase Purification Strategy can be considered.Three Phase Purification Strategy Imagine the purification has three phases Capture, IntermediatePurification and Polishing.In the Three Phase Strategy specific objectives are assigned to each step within the process:In the capture phase the objectives are to isolate, concentrate and stabilise the target product.During the intermediate purification phase the objective is to remove most of the bulk impurities such as other proteins and nucleic acids, endotoxins and viruses.In the polishing phase the objective is to achieve high purity by removing any remaining trace impurities or closely related substances.The selection and optimum combination of purification techniques for Capture,Intermediate Purification and Polishing is crucial to ensure fast method development, a shorter time to pure product and good economy.108060402012345678Number of steps 95% / step90% / step 85% / step 80% / step 75% / stepYield (%)The final purification process should ideally consist of sample preparation, including extraction and clarification when required, followed by three major purification steps, as shown in Figure 2. The number of steps used will always depend upon the purity requirements and intended use for the protein.Fig. 2.Preparation and the Three Phase Purification Strategy11Guidelines for Protein PurificationThe guidelines for protein purification shown here can be applied to any purification process and are a suggestion as to how a systematic approach can be applied to the development of an effective purification strategy. As a reminder these guidelines will be highlighted where appropriate throughout the following chapters.Define objectivesfor purity, activity and quantity required of final product to avoid over or under developing a methodDefine properties of target protein and critical impuritiesto simplify technique selection and optimisationDevelop analytical assaysfor fast detection of protein activity/recovery and to work efficientlyMinimise sample handling at every stageto avoid lengthy procedures which risk losing activity/reducing recovery Minimise use of additivesadditives may need to be removed in an extra purification step or may interfere with activity assaysRemove damaging contaminants earlyfor example, proteasesUse a different technique at each stepto take advantage of sample characteristics which can be used for separation (size, charge, hydrophobicity, ligand specificity)Minimise number of stepsextra steps reduce yield and increase time, combine steps logicallyKEEP IT SIMPLE!12Chapter 2PreparationBefore You StartThe need to obtain a protein, efficiently, economically and in sufficient purity and quantity, applies to any purification, from preparation of an enriched protein extract for biochemical characterisation to large scale production of a therapeutic recombinant protein. It is important to set objectives for purity and quantity, maintenance of biological activity and economy in terms of money and time. Purity requirements must take into consideration the nature of the source material, the intended use of the final product and any special safety issues. For example, it is important to differentiate between contaminants which must be removed and those which can be tolerated. Other factors can also influence the prioritisation of objectives. High yields are usually a key objective, but may be less crucial in cases where a sample is readily available or product is required only in small quantities. Extensive method development may be impossible without resources such as an ÄKTA™design chromatography system. Similarly, time pressure combined with a slow assay turnaround will steer towards less extensive scouting and optimisation. All information concerning properties of the target protein and contaminants will help during purification development, allowing faster and easier technique selection and optimisation, and avoiding conditions which may inactivate the target protein.Development of fast and reliable analytical assays is essential to follow the progress of the purification and assess effectiveness (yield, biological activity, recovery).Define objectivesGoal:To set minimum objectives for purity and quantity, maintenance of biological activity and economy in terms of money and time.Define purity requirements according to the final use of the product. Purity requirement examples are shown below.Extremely high > 99%Therapeutic use, in vivo studiesHigh 95- 99 %X-ray crystallography and most physico-chemicalcharacterisation methodsModerate < 95 %Antigen for antibody productionN-terminal sequencing13Identify 'key' contaminantsIdentify the nature of possible remaining contaminants as soon aspossible.The statement that a protein is >95% pure (i.e. target protein constitutes 95% of total protein) is far from a guarantee that the purity is sufficient for an intended application. The same is true for the common statement "the protein was homogenous by Coomassie™ stained SDS-PAGE". Purity of 95% may be acceptable if the remaining 5% consists of harmless impurities. However, even minor impurities which may be biologically active could cause significant problems in both research and therapeutic applications. It is therefore important to differentiate between contaminants which must be removed completely and those which can be reduced to acceptable levels. Since different types of starting material will contain different contaminant profiles they will present different contamination problems.It is better to over-purify than to under-purify.Although the number of purification steps should be minimised, thequality of the end product should not be compromised. Subsequent results might be questioned if sample purity is low and contaminants are unknown.Contaminants which degrade or inactivate the protein or interfere withanalyses should be removed as early as possible.The need to maintain biological activity must be considered at every stage during purification development. It is especially beneficial if proteases are removed and target protein transferred into a friendly environment during the first step.Economy is a very complex issue. In commercial production the time to market can override issues such as optimisation for recovery, capacity or speed. Robustness and reliability are also of great concern since a batch failure can have major consequences.It may be necessary to use analytical techniques targetted towards specific conta-minants in order to demonstrate that they have been removed to acceptable levels. 14Define properties of target protein and critical impurities Goal:To determine a 'stability window' for the target protein for easier selection and optimisation of techniques and to avoid protein inactivation during purification.Check target protein stability window for at least pH and ionic strength. All information concerning the target protein and contaminant properties will help to guide the choice of separation techniques and experimental conditions for purification. Database information for the target, or related proteins, may give size, isoelectric point (pI) and hydrophobicity or solubility data. Native one and two dimensional PAGE can indicate sample complexity and the properties of the target protein and major contaminants. Particularly important is a knowledge of the stability window of the protein so that irreversible inactivation is avoided. Itis advisable to check the target protein stability window for at least pH and ionic strength. Table 1 shows how different target protein properties can affect a purification strategy.Table 1.Protein properties and their effect on development of purification strategies.

The laboratory should have access to the following assays:• A rapid, reliable assay for the target protein• Purity determination• Total protein determination• Assays for impurities which must be removedThe importance of a reliable assay for the target protein cannot be over- emphasised. When testing chromatographic fractions ensure that the buffers used for separation do not interfere with the assay. Purity of the target protein is most often estimated by SDS-PAGE, capillary electrophoresis, reversed phase chromatography or mass spectrometry. Lowry or Bradford assays are used most frequently to determine the total protein.The Bradford assay is particularly suited to samples where there is a high lipid content which may interfere with the Lowry assay.For large scale protein purification the need to assay for target proteins and critical impurities is often essential. In practice, when a protein is purified for research purposes, it is too time consuming to identify and set up specific assays for harmful contaminants. A practical approach is to purify the protein to a certain level, and then perform SDS-PAGE after a storage period to check for protease cleavage. Suitable control experiments, included within assays forbio-activity, will help to indicate if impurities are interfering with results.Sample Extraction and Clarification Minimise sample handlingMinimise use of additivesRemove damaging contaminants earlyDefinition:Primary isolation of target protein from source material.Goal:Preparation of a clarified sample for further purification. Removal of particulate matter or other contaminants which are not compatible with chromatography.16The need for sample preparation prior to the first chromatographic step is dependent upon sample type. In some situations samples may be taken directly to the first capture step. For example cell culture supernatant can be applied directly to a suitable chromatographic matrix such as Sepharose™ Fast Flow and may require only a minor adjustment of the pH or ionic strength. However, it is most often essential to perform some form of sample extraction and clarification procedure.If sample extraction is required the chosen technique must be robust and suitable for all scales of purification likely to be used. It should be noted that a technique such as ammonium sulphate precipitation, commonly used in small scale, may be unsuitable for very large scale preparation. Choice of buffers and additives must be carefully considered if a purification is to be scaled up. In these cases inexpensive buffers, such as acetate or citrate, are preferable to the more complex compositions used in the laboratory. It should also be noted that dialysis and other common methods used for adjustment of sample conditions are unsuitable for very large or very small samples.For repeated purification, use an extraction and clarification techniquethat is robust and able to handle sample variability. This ensures areproducible product for the next purification step despite variability instarting material.Use additives only if essential for stabilisation of product or improvedextraction. Select those which are easily removed. Additives may need tobe removed in an extra purification step.Use pre-packed columns of Sephadex™ G-25 gel filtration media, forrapid sample clean-up at laboratory scale, as shown in Table 2.Table 2.Pre-packed columns for sample clean-up.Pre-packed column Sample volume Sample volume Code No.loading per run recovery per runHiPrep™Desalting 26/10 2.5 -15 ml7.5 - 20 ml17-5087-01HiTrap Desalting0.25 - 1.5 ml 1.0 - 2.0 ml17-1408-01Fast Desalting PC 3.2/100.05 - 0.2 ml0.2 - 0.3 ml17-0774-01PD-10 Desalting 1.5 - 2.5 ml 2.5 - 3.5 ml17-0851-01 Sephadex G-25 gel filtration media are used at laboratory and production scale for sample preparation and clarification of proteins >5000. Sample volumes of up to 30%, or in some cases, 40% of the total column volume are loaded. In a single step, the sample is desalted, exchanged into a new buffer, and low molecular weight materials are removed. The high volume capacity, relative insensitivity to sample concentration, and speed of this step enable very large sample volumes to be processed rapidly and efficiently. Using a high sample volume load results in a separation with minimal sample dilution (approximately 1:1.4). Chapter 8 contains further details on sample storage, extraction and clarification procedures.17Sephadex G-25 is also used for sample conditioning i.e. rapid adjustment of pH, buffer exchange and desalting between purification steps.Sephadex G-25 gel filtrationFor fast group separations between high and low molecular weight substances Typical flow velocity 60 cm/h (Sephadex G-25 SuperFine, Sephadex G-25 Fine), 150 cm/h (Sephadex G-25 Medium).If large sample volumes will be handled or the method scaled-up in the future, consider using STREAMLINE™ expanded bed adsorption. This technique is particularly suited for large scale recombinant protein and monoclonal antibody purification. The crude sample containing particles can be applied to the expanded bed without filtration or centrifugation. STREAMLINE adsorbents are specially designed for use in STREAMLINE columns. Together they enable the high flow rates needed for high productivity in industrial applications of fluidised beds. The technique requires no sample clean up and so combines sample preparation and capture in a single step. Crude sample is applied to an expanded bed STREAMLINE media. Target proteins are captured whilst cell debris, cells, particulate matter, whole cells, and contaminants pass through. Flow is reversed and the target proteins are desorbed in the elution buffer.STREAMLINE (IEX, AC, HIC)For sample clean-up and capture direct from crude sample.STREAMLINE adsorbents are designed to handle feed directly from both fermentation homogenate and crude feedstock from cell culture/fermentation at flow velocities of 200 - 500 cm/h, according to type and application.Particle size: 200 µmNote:cm/h: flow velocity (linear flow rate) = volumetric flow rate/cross sectional area of column.18Chapter 3Three Phase Purification StrategyPrinciplesWith background information, assays, and sample preparation and extraction procedures in place the Three Phase Purification Strategy can be applied (Figure 3). This strategy is used as an aid to the development of purification processes for therapeutic proteins in the pharmaceutical industry and is equally efficient as an aid when developing purification schemes in the research laboratory.Fig. 3.Preparation and the Three Phase Purification Strategy.Assign a specific objective to each step within the purification process.In the Three Phase Strategy a specific objective is assigned to each step. The purification problem associated with a particular step will depend greatly upon the properties of the starting material. Thus, the objective of a purification step will vary according to its position in the process i.e. at the beginning for isolation of product from crude sample, in the middle for further purification of partially purified sample, or at the end for final clean up of an almost pure product.The Three Phase Strategy ensures faster method development, a shorter time to pure product and good economy.In the capture phase the objectives are to isolate, concentrate and stabilise the target product. The product should be concentrated and transferred to an environment which will conserve potency/activity. At best, significant removal of other critical contaminants can also be achieved.19During the intermediate purification phase the objectives are to remove most of the bulk impurities,such as other proteins and nucleic acids, endotoxins and viruses.In the polishing phase most impurities have already been removed except for trace amounts or closely related substances. The objective is to achieve final purity.It should be noted that this Three Phase Strategy does not mean that all strategies must have three purification steps. For example, capture and intermediate purification may be achievable in a single step, as may intermediate purification and polishing. Similarly, purity demands may be so low that a rapid capture step is sufficient to achieve the desired result, or the purity of the starting material may be so high that only a polishing step is needed. For purification of therapeutic proteins a fourth or fifth purification step may be required to fulfil the highest purity and safety demands.The optimum selection and combination of purification techniques for Capture, Intermediate Purification and Polishing is crucial for an efficient purification process.Selection and Combination ofPurification TechniquesMinimise sample handlingMinimise number of stepsUse different techniques at each stepGoal:Fastest route to a product of required purity.For any chromatographic separation each different technique will offer different performance with respect to recovery, resolution, speed and capacity. A technique can be optimised to focus on one of these parameters, for example resolution, or to achieve the best balance between two parameters, such as speed and capacity.A separation optimised for one of these parameters will produce results quite different in appearance from those produced using the same technique, but focussed on an alternative parameter. See, for example, the results shown on page 49 where ion exchange is used for a capture and for a polishing step.20Select a technique to meet the objectives for the purification step. Capacity,in the simple model shown, refers to the amount of target protein loaded during purification. In some cases the amount of sample which can be loaded may be limited by volume (as in gel filtration) or by large amounts of contaminants rather than the amount of the target protein.Speed is of the highest importance at the beginning of a purification where contaminants such as proteases must be removed as quickly as possible. Recovery becomes increasingly important as the purification proceeds because of the increased value of the purified product. Recovery is influenced by destructive processes in the sample and unfavourable conditions on the column. Resolution is achieved by the selectivity of the technique and the efficiency of the chromatographic matrix to produce narrow peaks. In general, resolution is most difficult to achieve in the final stages of purification when impurities and target protein are likely to have very similar properties.Every technique offers a balance between resolution, speed, capacity and recovery and should be selected to meet the objectives for each purification step. In general, optimisation of any one of these four parameters can only be achieved at the expense of the others and a purification step will be a compromise. The importance of each parameter will vary depending on whether a purification step is used for capture, intermediate purification or polishing. This will steer the optimisation of the critical parameters, as well as the selection of the most suitable media for the step.Proteins are purified using chromatographic purification techniques which separate according to differences in specific properties, as shown in Table 3.

Beckman Coulter AU分析器的Prealbumin测定系统手册说明书
B AOSR6x75.01 OSR Special Chemistry 2009-08 PREALBUMINOSR6175 4 x 15 mL R1 4 x 6.5 mL R2Intended UseSystem reagent for the quantitative determination of Prealbumin (PALB) in human serum on Beckman Coulter AU analyzers.SummaryPrealbumin is a transport protein. It plays a significant role in the metabolism of vitamin A by complexing with retinol-binding protein which in turn complexes with Vitamin A transporting it through the body. This protein is an acute phase reactant whose levels fall in inflammation, malignancy, cirrhosis of the liver and protein wasting diseases of the gut or kidneys. Decreases are associated with liver disease and malnutrition. Levels of Prealbumin increase in Hodgkins disease.1,2MethodologyImmune complexes formed in solution scatter light in proportion to their size, shape and concentration. Turbidimeters measure the reduction of incident light due to reflection, absorption, or scatter.In the procedure, the measurement of the decrease in light transmitted (increase in absorbance) through particles suspended in solution as a result of complexes formed during the antigen-antibody reaction, is the basis of this assay.System Information For AU400/400e/480, AU600/640/640e/680, AU2700/5400 Beckman Coulter Analyzers. ReagentsFinal concentration of reactive ingredients:Solution of Polymers in Phosphate Buffered Saline (pH 7.1 – 7.3)Rabbit anti-human Prealbumin antiserumAlso contains preservatives.Precautions1. For in vitro diagnostic use.2. Do not ingest. Harmful if swallowed.3. Contains sodium azide as a preservative which may react with lead joints in copper plumbing to form explosive compounds. Even though thereagent contains minute quantities of sodium azide, drains should be well flushed with water when discarding the reagent.Preparation of reagentsThe Prealbumin reagent is ready for use. No preparation is required.Storage and stability1. The unopened reagents are stable until the expiration date printed on the label when stored at 2 - 8°C.2. Opened bottles of reagent are stable for 90 days when stored in the refrigerated compartment of the analyzer.Indications of DeteriorationVisible signs of microbial growth, turbidity, precipitate, or change in color in the Prealbumin reagents may indicate degradation and warrant discontinuation of use.Specimen Collection and PreparationFasting serum specimen, free from hemolysis, is the recommended specimen. Avoid highly lipemic samples, which may produce excessively high scatter signals.3Sample Storage and Stability Serum samples are stable 7 days when stored 2 - 8°C. These samples can be stored frozen (≤ -20°C ) for up to 2 months.Interfering Substances Results of studies conducted 4 show that the following substances may interfere with this Prealbumin procedure:The criteria for no significant interference is recovery within 10% of the initial value.Ascorbate: No significant interference up to 20 mg/dL AscorbateBilirubin: No significant interference up to 40 mg/dL BilirubinHemolysis: No significant interference up to 500 mg/dL HemolysateLipemia: No significant interference up to 500 mg/dL Intralipid** Intralipid, manufactured by KabiVitrium Inc., is a 20% IV fat emulsion used to emulate extremely turbid samples.The information presented is based on results from Beckman Coulter studies and is current at the date of publication.

For further information on interfering substances, refer to Young 5 for a compilation of reported interferences with this test.ProcedureA complete list of test parameters and operational procedure can be found in the User’s Guide appropriate to the analyzer.Materials ProvidedPrealbumin ReagentMaterials required but not providedPrealbumin Calibrator (Cat # ODR3029)PrealbuminB AOSR6x75.01 OSR Special Chemistry2009-08 Stability of Final Reaction Mixture The Beckman Coulter AU analyzers automatically compute every determination at the same time interval.CalibrationThe frequency of calibration for the Prealbumin turbidimetric procedure is every 90 days. Calibration of this Prealbumin procedure is accomplished by use of the Prealbumin Calibrator (Cat # ODR3029), which is traceable to IFCC International Reference Preparation CRM470 (RPPHS).Recalibration of this test is required when any of these conditions exist:1. A reagent lot number has changed or there is an observed shift in control values.2. Major preventative maintenance was performed on the analyzer.3. A critical part was replaced.Quality ControlDuring operation of the Beckman Coulter AU analyzer at least two levels of immunology control material should be tested a minimum of once a day. In addition, these controls should be performed after calibration, with each new lot of reagent, and after specific maintenance or troubleshooting steps described in the appropriate User’s Guide. Quality control testing should be performed in accordance with regulatory requirements and each laboratory’s standard procedure.Please note that recovery of Non-Beckman Coulter controls may vary with reagent lots of immunoassay products, due to the use of non-human materials in the controls.Results:Automatically printed out for each sample in mg/dL at 37°C.Dynamic RangeThe Prealbumin turbidimetric procedure is linear from 3 - 80 mg/dL. Samples exceeding the upper limit of linearity should be diluted and repeated. The sample may be diluted, repeated and multiplied by the dilution factor automatically utilizing the AUTO REPEAT RUN.Expected ValuesAdults:617 – 34 mg/dLExpected values may vary with age, sex, diet and geographical location. Each laboratory should determine its own expected values as dictated by good laboratory practice.Specific Performance CharacteristicsThe following data was obtained using the Prealbumin reagent on Beckman Coulter AU Analyzers according to established procedures.

USP 34 621 色谱法 中文译稿
<621>色谱法介绍色谱分离技术是通过样品组分在固定相和流动相两相中的分布差异进行分离的技术。
其中固定相可以是固体、有固相支持的液体或凝胶。
固定相可以填充于柱、分散成层、分布为膜或者应用于其他技术中。
流动相可以为气态、液态或超临界流体。
分离可以基于吸附性、质量分布(分配)或离子交换,也可以基于分子物理化学性质的差异,如大小、质量和体积。
本章节包括了基本步骤、定义和对一般参数的计算并描述了对于系统适应性的基本要求。
在USP中应用于定量和定性分析的色谱方法类型有柱色谱法、气象色谱法、纸色谱法、薄层色谱法(包括高效薄层色谱)和加压液相色谱法(一般称作高压或高效液相色谱)。
基本步骤本部分描述了使用某种色谱方法的基本步骤。
除另有各论规定外,以下色谱分离方法的步骤将会被遵循。
纸色谱法固定相:固定相为一张适当质地和厚度的纸。
色谱图的形成过程可以是上行的,这样溶剂被毛细管作用力支撑着沿着纸向上,这个过程也可以是下行的,在此情况下溶剂流动也受到重力的影响。
与溶剂流动有关的纸张纹理定向应该在一系列色谱图中保持恒定。
(纤维方向通常由制造商在色谱纸的包装上标出。
)仪器:纸色谱法的必备仪器包括装有添加溶剂的入口的气密室和短于该室内部高度5cm的耐腐蚀材料支架。
该支架作为用于溶剂槽以及用于抗虹吸棒的支撑,这些抗虹吸棒依次撑起色谱纸。
气密室的底部以规定的容积系统或流动相覆盖。
使用以规定溶剂系统润湿的纸张衬托于气密室的内壁,以增加气密室的溶剂蒸汽饱和度。
斑点:将待分析的一个或多个物质溶解于适当溶剂中。
以微量吸管吸取适当体积的溶液,其中通常含有1-20µg 该化合物,点样为6-10mm大小斑点且斑点间的间隔不小于3cm。
下行色谱法步骤1.带斑点的色谱纸以抗虹吸棒悬挂在气密室内,该棒将该色谱纸的上端固定在溶剂槽中。
(注:确保色谱纸挂在抗虹吸棒下的部分自由的悬挂在气密室中,没有接触到支架、室壁或室内的液体。
2.气密室被密闭,以便使该室与色谱纸达到溶剂蒸汽平衡(饱和)释放任何多余压力。

燃料电池加湿
某些类型的燃料电池需要对氢气和氧气流进行加湿以增加效能。虽然现存有很多技术能够加湿气
博纯的FC™系列加湿器符合行业标准,能提供无与伦比的稳定性和可靠 性,并具有很长的使用寿命。旨在满足用户对燃料电池的严格要求,FC 系列产品能为指定流量范围内的空气和氢气提供可持续且重复的加湿。 博纯加湿器特性为低压降,运行不需电力,大大减少系统的实际负载。 FC™系列具有坚固的可定制的外壳,以满足不同工况要求。FC™系列 加湿器是便携式、固定式、材料处理汽车和不间断电源等应用的良好选 择。在某些情况下,其运行寿命高达20,000小时。
气-气加湿模式采用反向流动的干湿气流,在运行中水份发 生交换。这种运行的能效很高,并不需要额外的加热。气- 气加湿模式有热交换的功能,可将湿气流中的大部分热量转 移到干燥的气流中。博纯大部分的加湿器都具有水-气及气-气 增湿功能(FC-100除外)。
湿度、压力和化学特性
Nafion®管在160℃时,化学性质依然稳定,且能够承受超过 8 0 p s i g 的 压 力 。 和 Te f l o n 一 样 , 它 的 化 学 惰 性 非 常 强 , 能 够 抵抗绝大多数化学物质的侵蚀。即使在高温下也能抵御高浓 度的腐蚀性气体如HCl、H2S和HF等。

Nafion® 优势
优势
● 和其他技术相比,博纯干燥器和加湿器对水份具有相当高的选择性 ● 在干燥过程中,可有选择性的完整保留工艺样气中的待测气体 ● 样气能够干燥至露点-45℃或加湿至100%RH。 ● 水份的转移在若干分之一秒内即完成 ● 整个运行过程连续且自我再生 ● 整套设备结构紧凑,牢固且具有极强的耐腐蚀性 ● 无活动部件,免日常维护 ● 干燥及加湿过程中无需使用电源,可适用于高防爆等级的危险区域
博纯加湿器既可以进行水-气增湿,也可以进行气-气增湿。 当进行水-气增湿时,水在干燥管外侧运行,样气在管内被 加湿。该种加湿方法能够产生最大的湿度,因为和水接触的 Nafion®管壁的磺酸基一直处于饱和状态,在此种加湿方法中, 可以用热水来增加加湿的效果。水从液相转为气相的过程中, 因为需要消耗能量,干燥管会自动降温而轻微地降低样气的湿 度,若不使用热水,会轻微降低水份交换的效率。

干燥器和加湿器工作原理
干燥原理
Nafion®加湿器
当气体通过Nafion®干燥管的时候,水份被管道内壁吸收并且通 过外壁渗出。除水的过程是靠管道内外的湿度差产生的,样气 中的水份在不到1秒钟的时间内就会从管内转移到管外。
大多数的博纯干燥器和加湿器内装有一根或多根Nafion®干燥 管并有一个外壳供吹扫气反向流动,这种管壳式的设计已被 证实其对于水份的转化十分有效。
除了Nafion®干燥管,博纯干燥管和加湿器还包括外壳和相应 的接头,在多管束系列中还使用了环氧树脂的连接头。单根 Nafion®管的干燥器和加湿器能够适应于任何接头。多管系列 的干燥管因为使用了环氧类的接头,在某种程度上惰性要差 一些。外壳和接头的材料可选用不锈钢,氟碳聚合物以及聚 丙烯等不同材质。
干燥器和加湿器的耐温性能取决于其制作材料,聚丙烯材料 最高可以耐温100℃,氟碳为150℃,不锈钢为160℃。若使 用多管系列,因为环氯树脂的原因,最高温度为150℃。若无 强化处理所有干燥管和加湿器的最大承受压力为80psig。具 体温度和压力请联系博纯销售代表。

吹扫气进口 干燥器和加湿器工作原理
快速 — 因为含有磺酸基团,Nafion®具有极强的渗水性。在此 化学结构中,磺酸基最多可以接受13个水份子。通过磺酸基 团,在Nafion®管壁上形成了一个交联的离子通道,水在管壁表 面经过磺酸基吸收后,通过离子通道迅速地转移至管壁的另一 面,然后蒸发。
选择性 — 与微孔渗透膜是一种相对较慢的扩散过程不同, Nafion®对水份的吸收和转移是非常迅速的水合过程。这是一个 只和水发生的特殊化学反应,其他物质通常不会受到影响。
过程简单 — 当水份在气相的状态下由管内转移到管外,没有自 由能的变化,所以不需要额外的能量来驱动该反应。反应的驱 动力来源于管内和管外的水份浓度差(湿度差)。
