前言用气相色谱法测定气体中微量硫化合物,一直是色谱分析的一个难题。早期的各种检测器如热导池、氩离子化检测器和微电量仪等,由于灵敏度不高或选择性不好,很难测出大量干扰组分存在下ppm级的个别硫化合物。1966年Brodey和Chaney提出火焰光度检测器(FPD)后,硫化物的色谱分析才有了较大的进展。 FPD是一种对含硫(磷)化合物具有高灵敏度和高选择性的检测器。其作用原理是在富氢
Preface Determination of trace sulfur compounds in gas by gas chromatography has been a challenge in chromatographic analysis. Early detectors such as thermal conductivity cells, argon ionization detectors, and microdialysometers, due to their low sensitivity or poor selectivity, were difficult to detect in ppm ppm of individual sulfur compounds in the presence of a large number of interfering components. In 1966, Brodey and Chaney proposed a Flame Photometric Detector (FPD), the chromatographic analysis of sulfide has made great progress. FPD is a detector with high sensitivity and selectivity to sulfur (phosphorus) compounds. Its principle of action is hydrogen-rich
