影响气相色谱定量准确度的实际因素

Practical Factors to the Accuracy of Quantitative Gas Chromatography

影响气相色谱定量准确度的实际因素很多。其中应把握两个线索：首先，试样中每个组分自始至终在数量和组分比例上均保持恒定（包括在色谱柱中通常应分离良好等）；其次，检测器线性范围应宽阔，因为宽阔线性常常比高灵敏度更为重要。

There are many factors that influence the accuracy of quantitative gas chromatography. Arnong them, it's principleto grasp two sides: the first, every component in the sample must keep constant quality and rate from beginning (including that thecomPonents' separation in column must be good normally); the second, detector linearity should be wide because wide linearity of-ten should be more important than high sensitivity.
