摘要
本文所介绍的是一种颇有特色的轻烃分析新技术。该方法与目前国内外所采用的轻烃分析技术有所不同,它是根据热力学中能量转换的原理,将原始岩样直接装入一密封的脱气装置筒内,在低真空负压下,利用高速旋转搅拌器,以实现岩石中轻烃的脱附。然后取出一定体积的脱附气送入高分辨率的毛细柱内,在最佳条件下进行色谱分离和鉴定及数据处理。
The new technique for analysing light hydrocarbons introduced in the paper is of characteristic, which differs from techniques currently used home and abroad. It is based on the principles of energy conversion in thermodynamics. Firstly an original rock sample is directly put into a tube of degasification device, and the deabsorption of light hydrocarbons under low vaccum negative pressure is accomplished by use of a high speed rotation agitator. Then certain volume of deabsorbed gas is injected into a capillary column of high resolution and chromatography and determination and data process are performed under optimum conditions.
