对于分析一般量的H_2S、SO_2等的气体色谱条件已有报导。对于复杂的气体混合物,必须获得所有组分的全分离或找到仅对硫有响应的选择性检测器才能进行分析。火焰光度检测器对硫有很好的选择性,样品在富氢的火焰中燃烧,其含硫成分以S_2的形式放射出394毫微米的特征光,灵敏度可达10~(-10)克/秒,能符合微量测定的要求。当然对于ppm级H_2S和SO_2的色谱分析,还必须重视这些活性气体在色谱系统上的吸附问题,但有人曾断言在普通
Gas chromatographic conditions for the analysis of typical amounts of H2S, SO2, etc. have been reported. For complex gas mixtures, it is necessary to achieve full separation of all components or to find a selective detector that responds only to sulfur for analysis. Flame photometric detector for sulfur has a good selectivity, the sample burns in the hydrogen-rich flame, the sulfur content in the form of S_2 emitted 394 nm characteristic light, the sensitivity of up to 10 ~ (-10) g / Sec, can meet the requirements of trace determination. Of course, for the chromatographic analysis of ppm-level H 2 S and SO 2, attention must also be paid to the adsorption problems of these active gases on the chromatographic system. However, it has been asserted that in general
