用气相色谱法测定矿物包裹体(简称包体)中气相成分以及用化学法测定液相成分,已有报导,但用同一份试样测定包体中气液成分的方法,却报导甚少。1982年有人虽提出用同一份试样测定包体中气、液成分的方法,但试样用量(20—50克)大,分析方法无突破性进展。近年来,由于离子色谱仪的出现,使无机痕量阴离子,特别是难分离的F~-、Cl~-、Br~-、
Gas chromatography has been reported for the determination of gas phase composition in mineral inclusions (inclusions) and for the determination of liquid components by chemical methods. However, the method for determining the gas-liquid composition in the inclusions using the same sample has been reported to a very small extent. Although it was proposed in 1982 with a sample of the same package gas and liquid components of the method, but the sample size (20-50 grams) large, no breakthrough in the analytical method. In recent years, due to the appearance of ion chromatography, inorganic trace anions, especially difficult to separate F ~ -, Cl ~ -, Br ~ -,
