Abstract: |
There is smaller amount of manual operation needed for an instrumental analysis with increasing instrumental automation level. So the influence of an instrumental status on the quality of testing results becomes bigger than ever before. In this work, the same sample was tested using different instruments under same chromatographic condition. Then the factors that create uncertainties in a whole determination process,which include concentration of standard solution, repeatability of measurement, linear fitting of the standard curve, and temperature variation, etc., were investigated and the results between different IC instruments were compared. |
