Abstract

A method for quantitative analysis of inert gases in liquids by gas chromatography is described. The technique comprises an equilibration system for partial extraction of dissolved gases from liquids and a gas chromatograph equipped with helium ionization detector. The method is particularly devised for determination of solubility coefficients of gases in liquid materials, e.g. water, aqueous solutions, blood, tissue homogenates, and for simultaneous measurement of several inert gases dissolved in liquids. Coefficients of variation for serial analyses of individual samples were less than or equal to 3%. The method is applicable to studies of blood-tissue transfer of respiratory and inert gases.

摘要

描述了一种通过气相色谱法对液体中的惰性气体进行定量分析的方法。该技术包括一个用于从液体中部分提取溶解气体的平衡系统和一台配备氦离子化检测器的气相色谱仪。该方法特别设计用于测定气体在液体材料（如水、水溶液、血液、组织匀浆）中的溶解度系数，以及同时测量溶解在液体中的几种惰性气体。单个样品连续分析的变异系数小于或等于3%。该方法适用于呼吸气体和惰性气体的血液-组织转移研究。
