| 气相色谱联机法测定矿物包裹体中的气体成分 |
| |
| 摘 要： | 本文提出了气相色谱联机测定矿物包裹体中气体成分的方法。该法是用两台气相色谱仪串联,由样品热爆炉、双分离柱、双热导池检定器和双记录仪组成的分析系统。它不用复杂的程序升温及分离柱切换技术,一次进样就可以连续地测定矿物包裹体中H_2、O_2、N_2、CH_4、C_2H_e、CO、CO_2、H_2O等气体组分。这种测定方法的变异系数小于4％,分析矿物包裹体中气体氢的灵敏度为7×10~(-3)μg。

| Abstract: | The present paper reports a new method to separate and determine traces of H2, O2, N2, CH4, C2H6, CO, CO2, and H2O in mineral inclusions by gas chromatography series connection system. The sensitivity of this method for hydrogen in mineral inclusions is 7 g.The variation coefficient of gas chromatography series connection system for determining eight components in mineral inclusions is about l-4%. |
