为了提取碳酸盐矿物包裹体中的气体成分,著者设计了一个微型真空研磨提取装置。本文研究了真空研磨装置的研磨效率、碳酸钙的热分解温度以及CO_2,CO,CH_4,O_2,N_2和H_2在样品表面上的吸附与解吸。制定了提取和测定碳酸盐矿物包裹体中气体成分的“真空研磨-气相色谱”方法实验证明,该方法不仅适用于碳酸盐矿物包裹体中气体的测定,而且也适用于石英和高温下易分解的矿物包裹体中气体的测定。
In order to extract the gas content of carbonate mineral inclusions, the authors designed a miniature vacuum grinding extraction device. In this paper, the grinding efficiency of vacuum grinding equipment, the thermal decomposition temperature of calcium carbonate and the adsorption and desorption of CO_2, CO, CH_4, O_2, N_2 and H_2 on the sample surface were studied. The “vacuum grinding - gas chromatography” method was developed to extract and measure the gas components of carbonate mineral inclusions. The method is not only suitable for the determination of gas in carbonate mineral inclusions, but also for quartz and high temperature Determination of gas in easily decomposable mineral inclusions.
