在空气分离装置中,往往由于烃类(尤其是乙炔)富集而引起爆炸。长期以来,人们试图寻找一种烃类杂质含量的快速测定方法。这方而的工作国内外已有许多报导。国内常用比色法测定乙炔含量。但此法不仅操作手续烦琐、准确度低,且对其它较活泼的烃不能同时测定。据资料报导,样品通过浓缩,采用色谱法 In air separation plants, explosions often result from the enrichment of hydrocarbons, especially acetylene. For a long time, people tried to find a rapid determination of hydrocarbon impurities content. There have been many reports of this work both at home and abroad. Domestic commonly used colorimetric determination of acetylene content. However, this method is not only cumbersome procedures, low accuracy, and other more lively hydrocarbons can not be measured at the same time. According to statistics, samples were concentrated and chromatographed
