Sulfide detection packed chromatographic column

Detailed information of sulfide detection packed chromatographic column:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for the determination of trace sulfides in sulfur recovery and hydrogenation process gas by combining two-dimensional gas chromatography center cutting technology with dual detectors. The target compound is separated by a pre column and enters the thermal conductivity detector. At the same time, the target compound is cut into the pulse flame photometric detector for detection through the auxiliary electronic gas path control system pressure change setting valve switching time. The retention time of H2S, SO2, COS, CH3SH, C2H5SH, and CS2 in the hydrogenation process gas was determined with and without column switching, and a dual column and dual detector qualitative and quantitative analysis method was established. This method is used for the analysis of hydrogenation process gas, and the relative standard deviation (RSD) of the target compound is<1.0%, with a minimum detection limit of<1 × 10-6 (volume fraction), linear correlation coefficient R ≥ 0.999 9. This method completely separates constant hydrogen sulfide from trace sulfide, saving H2S pre-treatment steps and solving the problem of accurate quantitative analysis of sulfur forms under the coexistence of H2S, trace SO2, and trace organic sulfur
