从350-kHz氦等离子体的原子发射进行了评估，用于计算的C/Cl和C/Br的比率，通过毛细管气相色谱分离的化合物。当血浆维持在0.32 mm内径的末端内时，在2 ml/min的GC载气+18ml/min的补充气（氦气）中，用熔融石英柱进行了分析，得到94%的元素比值与理论值的偏差小于20%。这些结果与柱上r.f.放电的数据与基于微波诱导等离子体的商业GC-原子发射检测系统获得的数据相当。
Atomic emission from a 350-kHz helium plasma was evaluated for the calculation of C/Cl and C/Br ratios in compounds separated by capillary gas chromatography. When the plasma was sustained inside the end of a 0.32 mm I.D. fused-silica GC column in 2 ml/min of GC carrier gas + 18 ml/min of make-up gas (helium), 94% of the elemental ratios obtained deviated by less than 20% from the theoretical values. These results with the on-column r.f. discharge were comparable to data obtained with a commercial GC-atomic emission detection system based on a microwave-induced plasma.
