用氣相色譜法分析氣體烴類的報導(dǎo)不少,但至今能夠達(dá)到實用程度的不多.近年來我國開始用“GDX”多孔微球來做固定相分離氣體烴類.由于“GDX”是自二乙烯基苯與苯乙烯,丙烯腈等物交聯(lián)聚合而成,可根據(jù)不同比表面積,選擇不同分析對象。

There are many reports on the analysis of gas hydrocarbons by gas chromatography, but so far it has not reached the practical level. In recent years, China has begun to use "GDX" porous microspheres as stationary phase to separate gas hydrocarbons. Because "GDX" is formed by cross-linking polymerization of divinylbenzene, styrene, acrylonitrile and other substances, different analysis objects can be selected according to different specific surface areas.
