各种物质中水分含量的分析,是生产和科学实验中经常遇到的问题。水分分析方法颇多,但气相包谱法具有分析速度快、灵敏度高、操作较方便等优点。几年来,笔者用气相色谱法对气体、液体、固体三形态物质中的水分分析做了一些工作。本文对其中一些主要问题作简单介绍。 1、分析方法气相色谱法测定物质中的水分,一般分转化法和直接法两类。转化法是将被测水分与某种试剂反应,生成可用更灵敏检测器来 Analysis of the moisture content of various substances is a frequently encountered problem in production and scientific experiments. There are many methods of water analysis, but the gas chromatography has the advantages of fast analysis, high sensitivity and convenient operation. Over the past few years, I used gas chromatography gas, liquid, solid three substances in the water analysis done some work. This article gives a brief introduction of some of the major issues. 1, analytical methods Determination of substances in water by gas chromatography, the general sub-transformation method and direct method of two categories. The conversion method is to react the measured water with a certain reagent to generate a more sensitive detector
