一、前言利用气相色谱法测定有机化合物中碳氢的燃烧产物始于六十年代初。由于测定快速因而得到迅速的发展。根据燃烧产物转化成的物质,设计了不同类型的仪器,大体可分为三类:①把水转化成适当的气体(H_2、C_2H_2、CO_2等),而后测定 CO_2和 H_2O 的转化产物;②先冷凝或吸附保留水分,进行二氧化碳的测定,而后放出水分,再进行测定;③直接 I. Introduction The determination of the combustion products of hydrocarbons in organic compounds by gas chromatography began in the early 1960s. As the determination of rapid and thus rapid development. Different types of instruments are designed according to the substances converted from the combustion products. They can be divided into three categories: (1) the water is converted into appropriate gases (H 2, C 2 H 2, CO 2, etc.), and then the conversion products of CO 2 and H 2 O are determined; Condensation or adsorption retention of water for carbon dioxide determination, and then release water, and then measured; ③ direct
