Determination of Trace Sulfide in Gas by Gas Chromatography
Determination of trace sulfides in coal gas by gas chromatography Details:

Name: Special column for sulfide

Stationary Phase: Dedicated

Specifications: 3m*3mm

Model: HH-sulfide-III

Application: Determination of 9 kinds of sulfides such as hydrogen sulfide, carbonyl sulfide, carbon disulfide, thiophene, methyl sulfide, methyl mercaptan, ethyl mercaptan, ethyl sulfide, dimethyl disulfide, etc.


In the process of methanol production, trace sulfides in the feed gas are one of the toxic substances. On the one hand, we must try to purify them. On the other hand, it is also very important to adopt accurate, reliable, rapid, advanced and automatic analysis methods. The method of determination of sulfide at home and abroad generally uses platinum as a catalyst and hydrogen reduction method, so that all organic sulfur is reduced to hydrogen sulfide, and then the total sulfur is measured by chemical analysis method. This method has poor accuracy, low sensitivity, and complicated operation procedures; the microcoulometric instrument is easily damaged and has poor reproducibility;

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography and selects pulsed flame photometric detector (PFPD) to analyze sulfide in gas on HH-sulfide-III sulfur chromatographic column. The method has high sensitivity and good selectivity , the results are accurate, the relative standard deviation is less than 1.1%.
