前言 用气相色谱法测定矿物包裹体中H_2、CO、CH_4、CO_2、H_2O等气体成分,近来有些报导,但是包括H_2O在内的以上气体成分的分析都是采用两种以上的方法或一个附有两根色谱柱的切换系统才能完成。本法的特点是采用一根1米长的TDX—01色谱柱,用氩为载气,热导池检测器,仅用0.2～0.5g的样品在半小时内就可以同时完成包裹体中H_2、CO、CH_4、CO_2、H_2O的提取,分离和测定。
Introduction Some gas compositions of H 2, CO, CH 4, CO 2 and H 2 O in mineral inclusions have been reported recently by gas chromatography. However, the analysis of the above gas composition including H 2 O is based on two or more methods or one Two column switching system can be completed. This method is characterized by the use of a 1-meter long TDX-01 column with argon as the carrier gas and the thermal conductivity detector. With a sample of only 0.2-0.5 g, it is possible to complete the H 2 , CO, CH_4, CO_2, H_2O extraction, separation and determination.
