Capillary Column Chromatography of Hydrogen Sulfide in Gas Details:

Stationary phase: dedicated
Specification: 30m*0.53mm
Model: HH-Sulfur-30
Application: H2S/COS/SO2/CS2 determination


Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. systematically studied the determination of hydrogen sulfide in gas by gas chromatography, and replaced the wet gas flow meter and absorption bottle with a highly inert polyvinyl fluoride (PVF) gas sampling bag, simplifying sampling. operating. The main sulfides of H_2S, COS, CS_2 and thiophene in coke oven gas were separated and analyzed by 60 m low sulfur capillary column and FPD detector. The optimized VI inlet and special sulfur passivation pipeline improve the sensitivity of the instrument, and the detection limit of the method can reach 1mg/Nm~3. Multi-point calibration and quadratic curve fitting were used. The measurement range was from 10 mg/Nm~3 to 300 mg/Nm~3, and the hydrogen sulfide in the gas was compared by iodometric method. After precision test, the accuracy was verified. It proves that this method is simple, fast, accurate and reliable, and meets the requirements of trace analysis.
