由于气相色谱仪分析速度快、灵敏度高、分离效果好、分析周期短,近二十多年来,赢得了愈来愈多的用户。在石油化工、环境保护、医药卫生、生物化学等各个科研、生产部门的实验室中,气相色谱仪的数量与日俱增。特别是在石油化工部门的许多实验室、分析室中,气相色谱仪更是必不可少的分析工具。 Because of its advantages such as high speed of analysis, high sensitivity, good separation effect and short analysis period, GC has won more and more users in the recent two decades. In the petrochemical industry, environmental protection, medicine and health, biochemistry and other research and production departments of laboratories, the increasing number of gas chromatograph. Gas chromatographs are an essential analytical tool, especially in many laboratories and analytical laboratories in the petrochemical sector.
