摘要
在生烃动力学的研究中,需要对热模拟产生的少量或微量的烃类气体进行定性、定量分析及单体烃碳同位素分析。金管中的气体经托普勒汞泵收集定量后送入气相色谱仪进行成分分析,剩余的气体经收集、转移后进行碳同位素分析。文中介绍了系统的详细结构、工作原理,并讨论了影响分析精度的几个因素。
Abstract
In the study of hydrocarbon-generation dynamics, it is needed to make quantitative analysis, qualitative anakysis and simple-hydrocarbon carbon-isotopic analysis on minor or trace hydrocarbon gases generated from thermal simulation.The gases in gold tubes were collected and quantified by a Toepler mercury pump, and then were sent into a gas chromatogaph to make compositional analysis.The residual gases were collected and transferred so as to make carbon isotopic analysis.In this paper, the detailed structure and operating mechanism of the system were introduced, and several factors affecting analysis precision were discussed.
