前言在很多工业部门和科学研究单位需要对混合气中的含氧量进行连续自动分析。目前,氧气的自动分析方法大致分为两类:一类是化学——物理法,利用氧气和某种溶液起化学反应后产生的物理变化进行分析,如原电池法,去极化法,极谱法,光电比色法等;另一类是物理分析法,利用氧气的顺磁性进行分析。两种分析方法各有其独特之处,化学——物理法具有灵敏度高、选择性好的特点,但反应速度
Preface In many industries and scientific research institutes, the continuous and automatic analysis of oxygen content in the mixture is required. Currently, the automatic analysis of oxygen can be divided into two categories: one is the chemical-physical method, the use of oxygen and a solution from the chemical reaction of physical changes arising from the analysis, such as the original battery method, depolarization method, pole Spectroscopy, photoelectric colorimetry, etc .; the other is the physical analysis method, the use of oxygen paramagnetic analysis. Two analytical methods have their own unique characteristics, chemical - physical method with high sensitivity, good selectivity, but the reaction speed
