【摘要】 <正> 近几年来蒋孝忠等人建立了气相色谱测定岩石、矿物中二氧化碳的方法。但用峰高定量,仅适用于低量和中量二氧化碳的测定,对于含量高达百分之几十的矿物,如碳酸盐类等矿物中二氧化碳的测定则较为困难。为了满足测量范围,真正达到简便、快速、准确的要求,我们在原方法的基础上利用微型计算机,用峰面积定量,单点校正法进行计算。在进样期更多还原

【Abstract】 Described in this paper is a new approach for directly determining CO₂ at the miligram levels in rocks and minerals by using gas chromatograph on the basis of electronic computer. In addition to such advantages as rapidity, simplicity and small sample repuirement, the method can satisfy the determinationof CO₂ at various levels in the samples with high accuracy.更多还原
