CIC-200离子色谱仪高浓度离子水样观测实验

The experiments of using CIC-200 ion chromatograph for the high concentration ion water sample

CIC-200型离子色谱仪观测高浓度离子水样时,对水样稀释500—1 000倍,但观测误差大。考虑仪器观测的精密度,兼顾各离子正常图谱形态,福州地震台对高浓度离子水样进行不同倍数稀释实验,即进行高浓度标准溶液和标准添加的准确度和精密度实验,结果均满足国标要求,说明CIC-200离子色谱仪观测高浓度离子水样是可行的。

The method is supported by the factory manufacture to dilute the high concentration ion watersample 500-1 000 times when the sample is measured by CIC-200 model ion chromatograph.But the test results deviation is big. There are the experiments of the high concentration ionwater sample by diluted at distinct multiples in Fujian station, which is considered both thechromatograph of the accurate and precision and the normal atlas shape of the ions. Which theexperiment of result is analyzed at the accurate and precision is satisfied with the national standardthrough the experiment of the high concentration standard solution and the standard addition.
