DO NOT use abrasive, flammable liquids, cleaning solvents, or strong detergents as they may damage the finish, impair safety, or affect the reliability of the structural components.Cleaning the WVG2 Vacuum SensorIf the vacuum sensor becomes contaminated with oil, follow this procedure:1. Power off the WVG22. Carefully shake the gauge to remove any large quantities of oil from the sensor3. Apply a few drops of rubbing alcohol inside the vacuum port(DO NOT INSERT ANY OBJECT INTO PORT, AS THIS WILL PERMATENTLTLY DAMAGE THE SENSOR)4. Place your finger over the port and shake for 30 seconds5. Remove your finger and allow alcohol to flow out the sensor part6. Repeat steps 3 to 5 at least three times7. Allow the sensor to air dry over at least an hour, or pull a vacuum on the sensor to to. Dry it more quickly8.Power on the WVG2, which should be ready for use.NOTE: It is important to remove all the vapors from the sensor, either through air-drying or via vacuum. Any remaining vapors will cause an incorrect readingDisposalCleaningStorageRemove the batteries when instrument is not in use for a prolonged period of time.

如果要求测试参数与当前状态相符时，便可进行测试。
否则应通过键盘重新设置。
3．设置测试参数具体详情见HLN-里氏硬度计使用说明书。
4．进行测试测试前如有必要可先使用校验试块对仪器进行检验。
（要求每星期进行一次校验）随机试块的数值是用标定过的里氏硬度计，在其上垂直向下测定5 次，取其算术平均值作为随机试块的硬度值。
4．1加载向下推动加载套，使冲击体被锁住。
见图（1）图（1）图（2）图（3）4．2 定位将冲击装置下部的支承环压紧在被测表面，要求每处被测表面的测试不低于三次。

此时要求被测工件、冲击装置、操作者均稳定，并且作用力方向应通过冲击装置轴线。
见图（3）每次测试结束后，示值显示区便显示出该次测试的硬度值或强度值，同时测试次数增一。
注：若测试值显示“E”，表示超出换算范围，则本次测试无效。
测试次数显示区显示的数字不变。
5．显示本组平均值测试值应是3～5 次或更多次测试的平均值，但每组测试次数不能超过9 次，否则，前9 次测试值不予保留。
按ENTER AVERAGE键，示值显示区便会显示出本组测试的硬度或强度的平均值，同时在测试次数显示区的左下角出现“Ave”提示符号，本组测试结束，再按ENTER AVERAGE键，将开始下一组的测试。
6．检查测试结果按DELETE 键，可查看前一次的测试结果，按ENTER AVERAGE键，可查看后一次的测试结果。
偏差太大的测试值可在按DELETE键的同时按O STATE键，将其删除，则该次测试值不打印且不参与平均值计算。

示差检测器原理
在应用开始前，使用流动相冲洗样品池和参比池。然后关闭参比池，让溶剂仅从样品 池中流过。流动相在两个池中旳示差折光相同，而且能够调整零点玻璃旳位置，使检测器 能够到达光平衡，让每个二极管取得一样旳光线量。 当样品经过色谱柱旳洗脱流入样品池时，样品池中旳内容物旳示差折光就会发生变化。示 差折光旳变化会造成光束经过流通池时发生偏转，成果使两个二极管取得旳光线量不相等。 此操作所造成旳二极管电流变化经过放大后能够用于生成经过校正旳检测器信号。该信号 （以示差折光单位旳十亿分之[nRIU] 为单位）与样品池中旳样品和参比池中旳流动相旳示 差折光差别相相应。

国Ⅵ柴油中多环芳烃含量的检测方法
1.4 试验步骤SH/T 0806-2008高效液相色谱示差检测法检测车用柴油中多环芳烃含量，用SH/T 0806石科院系统验证标准溶液(SPS)作为实验样品，从示差检测器温度、色谱柱柱温、流动相的流速等影响因素进行实验，对分析方法的操作条件进行探究。
SH/T0806—2008高效液相色谱示差检测法规程要求操作条件必须保证环己烷和邻二甲苯的分辨率不小于5.0[3]。
2 结果讨论2.1 影响因素的考察(1)示差检测器温度。
示差检测器对温度极其敏感，对环境温度的稳定要求比较高，通常示差检测器温度设定比室温高5℃[4]，此次实验环境的温控条件不是很好，夏天在空调全开的情况下室温可能达到30℃。
因此，将示差检测器温度设定在35℃。
(2)色谱柱温度。
进样量选择规程推荐值10μL，流动相流速建议是1.0±0.2mL/min，初始状态选择中间值1.0mL/min，色谱柱温度(柱温)从20℃以每次5℃为梯度到40℃进行实验。
实验结果如表1所示。
表1 色谱柱温度影响结果210 1.025 6.22 6.592310 1.030 5.86 6.299410 1.035 5.45 6.032510 1.040 5.17 5.823由表1可以看出，当柱温在20℃的时候柱分辨率较大，非芳烃、单环芳烃、双环芳烃和三环芳烃的分离度较好。
这是因为0 引言车用柴油中的多环芳烃含量直接影响柴油的十六烷值、尾气排放中的氮氧化合物和固体颗粒污染物[1]。
国家发改委等七部门宣布自2019年1月1日起全面供应“国六标准(国Ⅵ)”车用柴油，多环芳烃的控制指标由国五的11%(质量百分数)下降到国六的7%，并将气质联用法改为“SH/0806中间馏分芳烃含量的测定示差折光检测器液相色谱法”作为仲裁方法。
多环芳烃是一类芳香族有机化合物，具有很强的致癌性，可以通过呼吸或者直接的皮肤接触使人体致癌。
因此，在提倡健康环保的今天，控制柴油中的多环芳烃含量，有着重要的意义[2]。
RID示差检测器操作规程
RID示差检测器操作规程RID示差检测器操作规程当检测的样品可能会有无紫外吸收的成分如萜类及皂苷时，可选用此检测器。
一、操作步骤1、按shift 和8R flow 以冲洗参比池流路20min，此时，R flow 灯亮。
2、反复开关R flow数次以消除池内气泡。
3、关闭R flow，等待至基线稳定。
4、当blance value大于50时，按blance键平衡光路。
（如小于50，不必此操作。
）5、等待基线稳定后，开始分析。
二、要得到稳定基线，应注意：1、保持室温恒定2、溶剂脱气以减少溶剂内溶解的气体3、连接大内径废液管以降低检测器出口背压系统内无在线脱气装置时，一般使用0.3 mmid废液管已产生一定背压而避免生成气泡，但有可能对基线稳定性产生影响。
故一般建议配备在线脱气装置且使用大内径废液管。
三、注意点1、大流量操作条件（L模式）下，开关电磁阀（R flow）可能会损坏电磁阀，此时会显示CHECK FLOW信息。
此时应将流量设定为1mL/min，再按Enter。
2、反复按FUNC键至显示TOTAL EN，此能量为照射至二极管上的总光能量，一般为6000～9000，如不在此范围时，调节LAMP Volt使之落于该范围。
3、当流量大于3mL/min时，应关闭检测池温度控制，即CELL TEMP：OFF。
如流量小于3mL/min时，设置CELL TEMP为室温＋12℃。
温度设置范围为30-60℃。
检测器实际温度可在ACT TEMP下显示。
4、注意背压：检测池：≦ 20kgf/cm2四、清洗检测池在R flow处于ON时，从进口处注入50mL丙酮，再依次用50mL 蒸馏水、50mL 0.1mol/L硝酸溶液进行冲洗，再用蒸馏水冲洗干净。

示差折光检测器使用说明(原理)教学内容
示差折光检测器使用说明(原理)1.基本原理示差折光检测器是基于连续测定流通池中溶液折射率的方法来测定样品浓度的检测器。
光从一种介质进入另一种介质时，由于两种物质折射率的不同就会产生折射。
只要样品组分与流动相的折光指数不同，就可被检测，二者相差愈大，灵敏度就愈高，在一定浓度范围内检测器的输出与溶质浓度成正比。
溶液的折射率是纯溶剂（流动相）和纯溶质（样品）的折射率乘以各物质的浓度之和。
1.1光学系统在偏转式示差折光检测器中，光路在通过两个装有不同液体的检测池时发生偏转，偏转的大小与两种液体之间折光率的差异成比例。
光路的偏转由光敏原件上的位移测得，显示了折光率的不同。
