土壤热蒸发气气相色谱分析实验及地球化学特征──热蒸发制备仪简介

Gas chromatographic analysis and geochemical characteristic of gas from soil thermal vaporization

文章简要介绍了自行研制的热蒸发气制备仪，实验选择了土壤样品制备与气相色谱分析条件，探讨了不同制备条件对组分的影响及特征，并与酸解烃进行对比；探讨了土壤热蒸发烃、氢油气地球化学特征。该方法有快速、廉价、有效、无污染等特点，是地表地球化学勘探的一种新方法。

The thermal vaporization device is breifly introduced in this paper.Soil samples and analytical conditions of gas chromatography are selected in the experiments. And the affections on the composition of gases under different experiment conditions are discussed. Compared with foe acidolysis hydrocarbon,geochemical characteristics of hydrocarbon gas and hydrogen gas are described. This method is rapid,cheap,effective and non-pollution and is a new technology of surface geochemical exploration.
