摘要
目的 研究汽车怠速排放成分快捷准确的分析方法方法 设计了气路系统,采用柱切换技术,利用053mm×40m去活化Al2O3,毛细管柱分离碳氢化合物,利用2mPropackT和15m13X分子筛填充柱分离永久性气体结果 只需一次进样即可同时对汽车怠速排放物中的O2,CO,CO2和C1～C4烃中9种化合物进行定性和定量分析在汽车尾气碳氢混合物中共检测出了40个峰结论 本文研究的分析方法,操作简便。
Aim To investigate an accurate analytical method for automotive exhaust gases. Methods Multi dimensional switching system was designed. And a 0 53 mm× 40 m big bore Al 2O 3 capillary was employed for the separation of hydrocarbons, and two stuck columns, i.e. 2 m propack T and 1 5 m 13X molecular sieve, for the separation of permanent gases. Results 12 species, i.e. O 2,CO,CO 2 and 9 components among hydrocarbons without more than 4 carbon atoms can be detected quantitatively with only one sampling, and 40 chromatography peaks were obtained in the automotive exhaust gases. Conclusion The analytical method worked out in this thesis is proved practical and reliable.
