MSD的基础知识
引言
随着电子技术的不断发展，人们对电子产品的可靠性越来越关注，这同样促使制造厂商对潮湿敏感器件（moisture-sensitive devices，简称MSD）的关注程度不断上升。在以往的电子组装过程中，这些可能都不是问题。但是随着元器件朝着小型化和廉价化方向的发展，塑料封装已经成为了常规做法。这时，确保潮湿气体不会进入器件内部就非常重要。因为潮湿气体会对MSD产生影响,造成产品进行返修甚至要废弃该组装件。更为重要的是那些看不见的、潜在的缺陷，这些有可能对产品的可靠性造成严重的威胁。相对于十几年的ESD有关的问题，企业普遍都对潮湿问题缺乏理解和控制，它不仅是制造问题，更重要的是设计选型的问题。随着塑料封装的普及，塑料封装所引起的MSD失效率已经越来越突出，该问题已经成为塑料封装三大问题之一，再加上芯片集成度越来越高，特征尺寸越来越小，每一年半就翻一翻，集成电路功率越来越高，IC封装成本已经成为微电子发展的瓶颈。在封装成本的压力下，封装材料及引线等技术在不断变化。以上挑战造成MSD问题越来越突出,已经成为影响产品可靠性重要因素之一。

CE-MSD

CE and CE/MS for the analysis of natural productsApplicationGordon Ross, Yi Li andCarsten BuhlmannNatural products have played a major role in human health care for centuries. The discovery that compounds from natural sources arehighly effective against “modern” disease, such as breast cancer, in combination with the realization that there are thousands of uncharac-terised and even unknown species still to be investigated, means thatthe analytical investigation of natural products is of great importance. Whether the source is animal or plant, it is frequently the case that the effective components are present in a rich matrix of other compounds. This presents specialized problems to the investigating scientist. Notonly should the separation technique employed be capable of high reso-lution and high efficiency separations, the detection technique chosen should be highly selective and hopefully capable of providing as much identification data points as possible.Capillary electrophoresis (CE) is a high efficiency, high resolution tech-nique with the added benefits of being able to handle very complex matrices. Since CE is performed using an open tube of very small diameter, it is not prone to fouling as is an LC column, and can easilybe washed by flushing to prevent carryover. This makes the system inherently more robust, more reliable and reduces the sample prepara-tion required. In this application note we show a number of applica-tions demonstrating the utility of CE with UV and MS detection for the analysis, component identification and quantification, and characteriza-tion of traditional Chinese medicines.Mahuang (Ephedra sinica stapf )is a Chinese herbal medicine com-monly used in the treatment of asthma and respiratorial infec-tions. Its active ingredients (ephedrine, norephedrine, psu-doephedrine and norpseu-doephedrine) are strong central nervous system stimulants.Mahuang can be used alone or to potentiate the effects of other herbal medicines. In order to eval-uate the herbal quality, HPLC maythreaded through the UV detector interface before leaving the instru-ment for MS connection thus pro-viding tandem UV and MS detec-tion.Mass SpectrometryAn Agilent 1100 series MSD single quadrupole mass spectrometer was used for all CE/MS analyses.An Agilent CE/MS sprayer kit (Agi-lent part number G1607A) was used to couple the CE with MS using electrospray ionization (ESI). The sprayer was of a triple tube design accommodating theseparation capillary, a tube for delivery of sheath liquid and an outer tube for delivery of the neb-ulizing gas and is arranged orthog-onal to the MS entrance capillary in the ion source. The sheath liq-uid was delivered by an Agilent 1100 Series isocratic LC pump equipped with a 1:100 splitter. The traditional medicines samples used in the described applications were the kind gift of Professor Liu, Peking University, Beijing-PRC.ExperimentalCapillary Electrophoresis All analyses were performed using the Agilent Capillary Elec-trophoresis system which isequipped with diode array detec-tion and controlled by the Agilent ChemStation software. For CE/MS analyses the CE instrument was fitted with the CE-MS adapter kit (Agilent part number G1603A) which prepares the CE for coupling with the MS.This includes an MS cassettewhich allows the capillary to beCE conditions Capillary:80.5 cm (72 cm) × 75 µm Buffer:25 mM borate pH 9.3Detection:200/10 nm Injection:500 mbar · s Voltage:30 kV Temperature:20 °CFigure 1Analysis of a Muhuang extractbe used to determine the concen-trations of these active ingredi-ents. However, this is complicated by the long run time necessary (30minutes) and contamination of the LC column. The LC method is also a gradient method which requires column re-equilibration and wash-ing between runs. The CE method described here is simple and rapid requiring only a four-minute capil-lary wash between runs.Sample extraction1 g herb extracted with 20 ml water and heated to 80°C for 30 minutes then filtered through 0.2 µm pore and injected.ResultsFigure 1 shows the separation of Mahuang extract. The ephedrine peak appears after approximately 6 minutes but the rest of the sam-ple shows an enormous complexi-ty. If using LC, the remaining1. Identification of Ephedrine in Mahuangsample must be washed from the column after detection of the active ingredients. However in CE, the capillary is simply flushed through with fresh buffer. Figure 2 shows the analysis of a standard solution of ephedrine and a Mahuang extract and compares the spectra of the indicated peaks. Ephedrine could therefore be identified by its spectra and its migration time and confirmed by spiking with a known standard. For ephedrine the analysis was linear over the range 1 µg/ml to1 mg/ml with r2= 0.9995.Figure 2Comparing the spectra of ephedrine in Mahuang with that of a standard2. Identification and quantitation of the alkaloids berberine, palmatine and jatrorrhizine in Mahonia stemMany species of the Mahonia plant are used in China as traditional medicines. Some of the active components have been identified as alkaloids and pharmacological research has determined that the plant has antibacterial, antioxi-dant, antifungal, anticancer and antiproliferative properties. Here we describe the quantitation of three alkaloids in the stem of vari-ous Mahonia species. Sample extraction2 g of pulverized Mahonia stem was ultrasonicated in 10 ml methanol for 30 minutes. This was repeated twice using 5 ml methanol and ultrasonicated for 20 minutes. The combined extracts were centrifuged for 10 minutes (4000 rpm) and filtered through a 0.45-µm membrane before injection.Prior to each run the capillary was flushed for two minutes with 0.1 M NaOH, two minutes with water and five minutes with buffer. Replenishment of buffer vials was performed every 6th run to achieve best reproduceability.ResultsA typical separation of a Mahonia stem is shown in figure 3. Detec-tion at 265 nm confers some selec-tivity on the analysis and the three alkaloids berberine, palmatine and jatrorrhizine are well separated from other sample matrix compo-nents which absorb at that wave-length. Detection at 200 nm illus-trates the complexity of the sam-ple matrix. These three alkaloidscan be automatically detected and identified by spectral librarysearch using a library constructed from standards (figure 4). Detection of berberine, palmatine and jatrorrhizine was linear over the ranges 3.4–109 mg/ml,1.4– 44 mg/ml and 1.1–37 mg/nl respectively with r 2better than 0.999 in all cases.CE conditions Capillary:50 µm id × 48.5 cm (40 cm effect.)Buffer:50 mM phosphate, 50 mM boratecontaining 50 % methanol with apparant pH adjusted to pH 8Detection:200/10 nm and 265/20 nm Injection:500 mbar · s Voltage:30 kV Temperature:20 °CFigure 3Analysis of Mahonia stem by CE with detec-tion at 200 nm and 265 nm897.677Figure 4Library search from separation of alkaloids in Mahonia stemFangchinoline and tetrandine are two alkaloids which are present in Radix Stephaniae tetradrae S.Moore . These compounds have pain-relieving activities, canreduce blood pressure, have anti-neoplastic and antibiotic activity and are therefore of pharmaceuti-cal interest. The plant is used in various Chinese herbal prepara-tions. Here we describe applica-tion of a CE method to quantita-tive analysis of these alkaloids in some traditional Chinese medi-cines.Sample extraction2 g of each pulverized herbal drug were extracted with 7 ml 50 %ethanol by stirring for 30 minutes followed by centrifugation (4000rpm, 10 minutes). The extraction was repeated a further two times and the combined extracts were filtered through 0.45-µm pore. For electrokinetic injection, a volume of 200 mM NaCl solution equiva-lent to one fifth of the sample vol-ume was added to the sample to equalize the sample conductivity.ResultsThe medicines were separated using a MEKC system with Tween-20 as the surfactant 2. This resulted in a very clean electropherogram where two peaks could easily be seen (figure 5). Due to their similar structure tetrandrine and fang-chi-noline (figure 6) have very similar spectra and therefore were identi-fied by spiking experiments with pure standards. After identification the two alkaloids were quantified in a number of traditional Chinese medicines. Linearity was deter-mined for both compounds over the range of 5 to 250 µg /ml. Linear-ity was greater than 0.9999 for both analytes. Reproducibility of migra-tion times was very good (< 0.4 %).For quantitation, the reproducibili-ty of peak areas was acceptable (<4 %) but depended on the medicine and therefore the sample matrix (table 1).3.

All three of these sub-stances naturally occur in many plants. For example, CA which is present in the surface skin of peaches, inhibits the cutin-digest-ing enzyme of the brown rot fun-gus, Monilinia fructicola demon-strating its antifungal activity. It has also been demonstrated to have antioxidant activity. CA is an active consituent of Flor. Lonicer-ae and CZE has been used for its analysis in the plant and in some traditional medicines which con-tain this plant as a constituent 3.Here we describe how CA can be identified and quantified in some Chinese traditional medicines using capillary electrophoresis.Sample ExtractionWeighed amounts of pulverized samples were soaked with 7 ml 50 % ethanol/water overnight and extracted by stirring for 30 mintes.After centrifugation (4000 rpm, 10 minutes) the extraction was repeated two more times. The combined extraction volume was made up to 25 ml and filtered through 0,45 µm. Liquid samples were simply diluted and filtered before measurement.4.

Iden-tification of CA is made more problematic because when inject-ed individually as a standard it migrates in an area occupied in the sample injection by three peaks, all of which have similarspectra. By spiking samples with pure CA it can be unequivocally identified in the prepared TCM extract (figure 9). Table 2 shows the calculated amounts of CA in Flor Lonicerae , some TCMs and in a coffee extract.[min][min]1020Shung huang lian could be separated in chlorogenic acid and two similar phenolic acids Shung huang lian sample was spiked with 5 times the amount of chlorogenic acidFigure 9Identification of cholorogenic acid in a traditional Chinese medicine by spiking with a pure standardChlorogenic acid Powder weight (g)Content (mg/g)(mg/L)or (mg/L)Flor Lonicerae 6700.94617.83Zhi I jin hua wan 61.18 3.340.49Vc yin qiao pain 104.1 2.830.85Yin qiao jie du pain542.9 2.9 3.5Xiao er qing re jie du kou fu ye 31.14liquid 0.39Shung huang lian187.8liquid 2.1Caf é (hot water extract)197.23liquid0.2Table 2Calculated amounts of CA in Flor Lonicerae , some TCMs and in a coffee extractAlthough CE can provide good resolution of these compounds in complex matrices (see section 3) one of its main limitations, when used with UV detection, is its rela-tively low sensitivity due to the short optical path length which is the capillary bore. These two alka-loids have extremely similar UV absorption spectra making their unequivocal identification via UV-spectral library search alone prob-lematic. The on-line coupling of CE with mass spectrometry (MS) is a promising combination. While CE provides high separation effi-ciency, MS affords high sensitivity and selectivity, as well as molecu-lar structural information. MS detection can provide unequivocal identification of the analytes by their masses.Successful coupling of CE to MS is dependent upon the efficiency of ions’ transfer from the aqueous to the gaseous phase. This, in turn, depends upon the volatility of the running buffer and therefore places some restrictions on the types and /or concentrations of buffer which can be used forCE/MS.The previous separation of tetran-drine and fangchinoline was only obtained using MEKC conditions, with a buffer solution of 60 mM triethylamine-phosphate contain-ing 50 mM Tween-20 and 20% methanol, where the analytes were separated according to dif-ferences in their hydrophobicity. However, such a running buffer is not suitable for ESI- CE/MS because its non-volatile compo-nents can hinder the electrospray process by reducing the spray effi-ciency and can cause intense background signals resulting in a decreased sensitivity in the TIC4. Further, these buffer components can contaminate the ESI interfaceand the MS ion optics, especiallywhere the spray is "in-line" withthe MS entrance capillary,although the orthogonal arrange-ment of the sprayer used in thisstudy can help to mitigate thiseffect5.In this application a method wasdeveloped for the CE/MS analysisof tetrandrine and fangchinoline inChinese herbal medicines, andtheir concentrations in some Chi-nese herbal medicines were deter-mined.ExperimentalThe preparations analyzed were:1) Fang ji guan jie wan:Radix Stepahniae tetrandrae(1.80 g), Poria (Poria cocos(Schw.) Wolf) (1.80 g), Rhizomaatractylodis macrocepahalae(Atractylodes macrocephalaKoidz) (1.2 g), Radix Aconiti (0.60g), Radix Glycyrrhizae (Gly-cyrrhiza uralensis Fisch.)

(5.83 g), Olibanum (Boswelliacarterii Bierdw.) (2.5 g), Myrrha(Commiphora myrha Engl.)(2.5 g), Radix Stephaniae teran-drae(2.5 g), Cortex periplocaeradicis (2.5 g) Rhizoma drynari-ae (Drynaria fortunei(Kunz) J.Sm.) (2.5 g).Sample preparationDifferent concentrations of tetran-drine and fangchinoline rangingfrom 0.2 µg/m to 200 µg/ml wereprepared by dissolving the stan-dard in 50 % aqueous ethanol solu-tion. Other samples were preparedas previously described.ResultsThe run buffer was chosen for itscompatibility with electrosprayionization. The separationachieved was not optimal howeverusing the second dimension of MSdetection ensured that the ana-lytes could be selectively detectedand identified.Linearity and detection limitsLinearity and limits of detectionwere determined for tetrandrineand fangchinoline. The low detec-tion limit and linear range of CE-MS indicate the possibility oftrace-level identification and quan-titative determination of tetran-drine and fangchinoline in Chineseherbal medicine. Detection waslinear over the range 0.2 to 200µg/ml for tetrandrine and fangchi-noline with r2values of 0.9991 and0.9986 respectively. The limits ofdetection were 3 µg/ml in TIC and0.05 µg/ml in SIM.RepeatabilityThe % relative standard deviationwas caculated for peak areas forfive replicate injections of stan-dard solution of 50 µg/ml. Repro-ducibility for fangchinoline was6.1 % while that for tetrandrine5. Analysis of tetrandrine and fangchinoline by CE/MSwas 5.9 %. The relatively poor repeatability of peak area by SIM compared to the results of the UV detection, which showed % RSD of ca. 3.1, was most probably due to variation in the efficiency of the ionization process. The crude drug of Radix Stephaniae tetrandrae and three Chinese herbal prepara-tions which contain Radix Stepha-niae tetrandrae were analyzed.Figure 10 shows that the presence of fangchinoline and tetrandrine in the herbal medicine “Qu feng gu tong lu” extract is unclear using CE-UV where the electrophero-gram contains a number of large and very small peaks. A number of other peaks are present in the area from two to four minutes in the UV trace, where the alkaloids’peaks are expected. However,using the SIM mode of MS the two alkaloids could be detected unam-biguously. The repeatability (% RSD, n=5) of peak area of fanchinoline and tetrandrine in “Qu feng gu tong lu” were 3.5 %and 4.3 % respectively.

ExperimentalTwo species of Mahonia: M. for-tunei and M. japonica were col-lected in China and identified by Beijing University of Chinese Med-icine.Sample preparationA 2.0 g sample of pulverised dried stem was extracted with 10 mL methanol by ultrasonication for 30min. Extraction was repeated a further twice with 5 mL methanol for 20 min. All methanol extracts were combined and centrifuged at 4000 rpm for 15 min, then filtered through a 0.45 µm filter.ResultsThe electropherograms of the extracts are shown in figure 11.The total ion electropherogram (TIE) is shown in the lower part and the UV signal in the upper part of the figures. The main peaks 1, 2, and 5 in the electro-pherogram could be identified as berberine, palmatine and jatror-rhizine. Peak assignment was per-formed by comparison of migra-tion time, UV spectrum and m/z with those of standards. Com-pound 4 showed a dominant signal at m/z 338 and was tentatively assigned as columbamine, which has been reported to exist in the genus of Mahonia. Compound 9showed a major signal at m/z 312and a minor one at m/z 623 indi-cating that it is an alkaloid with two nitrogens which exists both as a single protonated ion (m/z 623) and a double protonated ion (m/z 312). Therefore, it was tenta-tively assigned as isotetrandrine,which has also been reported to exist in the genus of Mahonia.Peaks 3, 6, 7 and 8 gave m/z values of 314, 305, 305 and 312 respec-tively. Since both berbamine and oxyacanthine have m/z of 305 and have been reported as present in Mahonia, peaks 6 and 7 could be assigned either as berbamine or oxyacanthine. Peak 3 and 8 could not be identified but due to their almost ubiquitous presence in a number of the species they were also monitored . Peaks 3, 6, 7, and 8 could not be unequivocally iden-tified but they could be specifical-ly characterized by their m/z and migration times.SIM mode was employed to detect all the putative alkaloid peaks which appeared in the TIC of the eight species of Manohia. Figure 12 shows the SIM signals obtained from analysis of these two Maho-6.

Since CE/MS is a two-dimensional separation technique,compounds with different µecould be resolved by electrophore-sis, while compounds with similar µe but different m/z could be selectively detected by using SIM mode. Therefore, although com-pounds 4 and 5, 6 and 7, and 8 and 9 have the same m/z, they could be separated based on differences in their various electrophoretic mobilities prior to SIM detection. Fingerprints of the two species of Mahonia were constructed by cal-culating the area of each alkaloid peak as a percentage of the total area of all nine peaks detected in SIM mode (figure 13). The profile of these nine peaks is quite differ-ent in these two species. Clearly the alkaloids berberine, palmatine and jatrorrhizine (peaks 1,2 and 5)are the most predominant, howev-er their proportions are quite dif-ferent and levels of the other ana-lytes help to further differentiatethese two species.Figure 12SIM traces from CE/MS of two species of MahoniaFigure 13Fingerprint of components of Mahonia species detected by CE/MS.

In combina-tion with DAD UV or MS detec-tion, components of these sample types can be clearly identified using a variety of techniques,spectral analysis, spiking with known standards, m/z determina-tion. The open tubular arrange-ment of CE makes it very suitable to the complex matrices which are encountered in the analysis of natural products. Coupling of CE with MS adds a second dimension of separation where analyteswhich have similar mobilities may be separated by the MS while iso-baric analytes require separation prior to their detection in the MS.References1.Li, Y., Ji, X., Liu, H., Yan, Y., Li, J.
