Gas hydrogen sulfide chromatographic analyzerThe principle:

After the gas sample to be analyzed passes through the chromatographic separation column, different sulfides enter at different timesFPD detector,As a result, chromatographic peaks with different retention times appear on the recorder,Because the response of sulfides is directly proportional to the square of sulfur concentration,So the corresponding sulfur concentration can be found on the pre prepared double logarithmic calibration curve based on the size of the chromatographic peak of the sulfide to be analyzed,Thus, quantitative analysis of sulfides can be conducted.
