Comparative Analysis of the Results of the Online Determination of Hydrogen Sulfide and the Results Obtained by Photometry and Chromatography–Mass Spectrometry

The results of the determination of sulfur-containing compounds in atmospheric air polluted by products of the depressurization of a product pipeline with gas condensate are presented. Hydrogen sulfide was determined online using mobile automatic control stations and by photometry in a stationary laboratory. Organic sulfur-containing compounds (mercaptans, sulfides, disulfides) were identified by chromatography–mass spectrometry. It was found that the results of the analysis obtained in the automatic mode reflect the total content of hydrogen sulfide and some organosulfur compounds.
