Analysis of H2S in Coke Oven Gas by Gas Chromatography
Gas Chromatography Analysis of H2S in Coke Oven Gas Details:

Capillary column 1: GS-GASPRO 30M*0.32MM
Capillary column 2: FFAP (polyethylene glycol) 30m*0.32mm*0.25um

This standard specifies the principles, instruments and materials, sampling, analysis procedures, calculation of results, precision and safety precautions for the determination of hydrogen sulfide in coke oven gas.
This standard applies to the determination of hydrogen sulfide content in coke oven gas.
Quantification: external standard method
Detector: FPD flame photometric detector

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. measured the H2S content in coke oven gas by GC- gas chromatograph with FPD detector from Haohao Chromatography E Co., Ltd., and compared the test data with the national standard iodine titration method. The results show that the analysis period of this method is shortened from 2 h to 10 min, and the H2S content in the gas is in the range of (5～5 000)×10^-6. The linear relationship is good, the accuracy is high, and the reproducibility Well, fully meet the H2S analysis requirements of different levels, it is a simple and rapid analysis method.
