浅谈火焰光度气相色谱法在不同气体总硫含量测定中的应用

Brief Discussion on the Application of Flame Photometric Gas Chromatography in Determination of Total Sulfur Content in Different Gases

目前常用紫外荧光法、氧化微库仑法等分析方法对气体中的总硫含量进行检测。研究火焰光度气相色谱法在气体中总硫含量测定中的应用,通过对氮气、氢气、空气和甲烷中的总硫含量进行色谱分析,得出火焰光度气相色谱法可适用于这些气体中总硫含量的检测,但是不同基底气体中总硫含量的检出限不同。

Currently,commonly used analytical methods such as ultraviolet fluorescence method and oxidative micro-coulomb method to detect total sulfur content in chemical industry gases.The paper studied the application of gas chromatography with flame photometric detector in the determination of total sulfur content in gas.Through the chromatographic analysis of total sulfur content in nitrogen,hydrogen,air and methane,it is concluded that flame photometric gas chromatography is suitable for the detection of total sulfur content in these gases,but the detection limits of total sulfur content in different base gases are different.
