摘要
对液氧中简单烃化物在低温下 (液氮环境 )进行浓缩富集 ,然后加热解析 ,用气相色谱进行分析 ,对液氧中可能存在的几种低级烃 (乙烷、乙烯、乙炔、丙烷、丙烯、正丁烷、异丁烷等 )可达到 10 - 6～ 10 - 9级的检测水平 ,其中乙炔可分离检测至 10 - 9级 .
The lower hydrocarbons in liquid oxygen was concentrated in liquid nitrogen atmosphere and then was warmed up to be analyzed with gas chromatography.Some possibly existing lower hydrocarbons(ethane,ethylene,ethine,propane,propylene,normal blutane,isoblutane,et al) can reach 10 -6 ～10 -9 level,ethine can be separated and determinated as low as 10 -9 level.
