1. Computrac的测试是定量分析、/strong>
2.测试时间和测试精?/strong>?CV = Coefficient of Variation 变异系数 = Repeatability重复性】：
a. 测试精度（重复性）的统计：Mean：平均值；S.D.：标准偏差；CV：变异系数，优于KF卡氏滴定泔br/> [Standard deviation（SD equal to or better than that of KF on comparable samples. With repeatability (Coefficient of Variation, CV) also equal to or better than KF on comparable samples. The previous test reports I provided you with will give you an excellent reference for what the customer can expect.]
b. 测试时间，一般测试时间不超过10分钟?nbsp;
(3-5 minutes for most Cathode materials. The previous test reports I provided you with will give you an excellent reference for what the customer can expect.)
3..采样环境９br/> a.针对低水分（少于1000ppm）或吸潮性较强的样品,我们建议露点 - 20 - 40的手套箱或干燥间内采
b.针对高水分（大于1000ppm）或吸潮性较弱的样品对采样环境没有特别要汁br/> (Our instrument does not require a lab, a chemist, or a dry room environment. The instrument can be used by anyone, on the production floor, in an office or in a lab. The only environment that should be specially considered is the environment that the sample needs. Some samples must be handled in a dry room or dry box because they absorb moisture very easily. With materials like that, you want to keep the Vapor pro in the same environment to make transferring of the material to the Vapor Pro easier.)
4.采样方法９/strong>测试时用金属瓶盖和无水硅酸垫?针对不同的样品有不同的采样方法：
a.极片: 样品称重后切成条后，加入样品瓶密封?nbsp;
例如：Cathode electrode
b.粉末: 样品称重后，加入样品瓶密封、br/> 例如９br/> Cathod Powder Carbon Sulfter Poly base (Vapor Pro,VPL)
LiCoO2 - Lithium Colbat Dioxide(Vapor Pro,VPL)
LiFePO4 (Vapor Pro,VPL)
LiH2PO4 - Lithium Phosphate monobasic(Vapor Pro,VPL)
LiNiCoO2 - Lithium Nickle Cobalt Dioxide(Vapor Pro,VPL)
LiV3O8 - Lithium Vandium Oxide (Vapor Pro,VPL)
c.液体: ?ml专用针筒采样，把样品滴进装有1CM X 4CM玻璃纤维滤膜的样品瓶后密封。加样前后的针筒都要称重，以确定加样重量、br/> 例如：Ionic Dielectric Liquid (Vapor Pro,VPL)
5.测量方法９br/> 不同样品有不同的测量方法(即测量程序，仪器可贮?02个测?测试程序)、br/> 例如９br/> Cathode electrode

6.工作原理９/strong>
（CTZ-V3100L Computrac Vapor Pro工作原理：）
CTZ-V3100L Computrac Vapor Pro利用了一个圆柱型的加热器、一个干燥气体—载体气体流动系统和一个水分传感器。仪器会对被装在带有隔膜?5ml玻璃瓶内的样品加热。从样品中挥发出来的物质会被送到装有相对湿度传感器（RH传感器）的感应区。用于检测蒸气中的水分的RH传感器是一个聚合物电容相对湿度传感器。传感器的读数、传感区温度和载体气流量经过微处利器以生成准确的样品水分含量 仪器可以显示
Parts per million (ppm) H2O
Microgram (ug) H2O or
Percentage (%) H20
The Vapor Pro uses a polymer capacitance sensor. This sensor changes capacitance as the dry carrier air containing water passes of the sensor. This change in capacitance is then translated into ug H2O, ppm H20, or % H2O. I have also attached a flow diagram to show the rest.
7. 测量步骤（CTZ-V3100L Computrac Vapor Pro测量步骤十分简单）９br/>
1? Weigh sample采样
2? Place sample in vial and load into Vapor Pro and press Start! 把样品放入样品瓶并置于仪器，按开始键，自动测试、自动结束并自动显示结果
