CS2 Sulfide Determination of Toxic Substances in Workplace Air Details:

Name: Packed column
Specification: 1.5m*4mm
Model: 2%OV-17/Chromosorb W 60-80 mesh
Application: GBZ/T 160.33-2004 Determination of Toxic Substances in Workplace Air Sulfide Carbon Disulfide

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography-triple quadrupole tandem mass spectrometry (GC-MS/MS) method for the determination of trace carbon disulfide in the air. Methods The chromatographic column was 2%OV-17/Chromosorb W 60-80 mesh, and the multi-reaction monitoring (MRM) scanning mode was used to study its optimized conditions. Results The response value of carbon disulfide has a good linear relationship with the concentration in the detection range, and the correlation coefficient is above 0.999 4. The minimum detection concentration of this method is 0.02 mg/m~3, the relative standard deviation is 0.4%~2.1%, and the recovery rate of standard addition is 88.3%~104.5%. Conclusion The established method solves the problems of serious interference, low response, and narrow linear range of national standard flame photometric detection (FPD) or mass spectrometry (MS) methods. It can be used for rapid qualitative and quantitative analysis of trace carbon disulfide in the air.
