【摘要】 本文主要介绍地质样品微量异烷烃和环烷烃的分析方法。该方法是从总烷烃馏份中分离出微量的异烷烃和环烷烃,单独进行气相色谱分析。为微量烃类的样品分离分析,特别是对有机质含量低、成熟度高的我国南方碳酸盐岩样品的分析,提供了新的分析技术和方法。更多还原

【Abstract】 An analysing method of trace isoalkanes and cycloalkanes in geosamples are introduced in this paper. Its process includes a separation of trace isoalkanes and cycloalkanes from the total alkane fraction, and henceafter a separate GC analysis. The method, being simple, capable of ultra micro -analysis and high efficiency of separation, provides new analytical techniques for micro-hydra carbon samples, particularly those sampled from marine carbonate rocks with low organic content and high maturity in the area of the southern China.更多还原
