微波诱导氦等离子体与原子发射光谱仪组成的原子发射检测器已用于农药的气相色谱分析。原则上，它可以检测周期表中任何能从气相色谱仪中分离出来的元素（氦除外）。发现C、H、D、N、O、Br、Cl、F、S、Si、P、Sn和Hg的检测限范围为0.1至75 pg/s，对碳的选择性为5000或更高。采用气相色谱-原子发射光谱检测系统对27种农药进行了检测和元素表征，获得了C、H、N、O、Br、Cl、F、P和S的元素特征谱图。通过对每种元素进行定量分析，可以计算出20种不同除草剂在两种不同混合物中的近似经验公式。采用气相色谱-原子发射检测法对掺有三种农药的苹果提取物进行了分析。
An atomic emission detector, consisting of a microwave-induced helium plasma and atomic emission spectrometer, has been used for the gas chromatographic analysis of pesticides. In principle, it is possiblr to detect any element in the periodic table (except helium) which can elute from a gas chromatograph. Detection limits for C, H, D, N, O, Br, Cl, F, S, Si, P, Sn and Hg were found to range from 0.1 to 75 pg/s with selectivities over carbon of 5000 or more. The gas chromatography—atomic emission detection system has been used for the detection and elemental characterization of 27 different pesticides by obtaining element-specific chromatograms for C, H, N, O, Br, Cl, F, P and S. By performing quantitative analysis for each element, it was possible to calculate the approximate empirical formulas for 20 different herbicides in two different mixtures. An extract from an apple doped with three pesticides was analyzed by gas chromatography—atomic emission detection.
