Determination of Toxic Substances in Workplace Air Part 38: Carbon Disulfide Details:

Name: Capillary Column
Specification: 30m*0.32mm*0.5um
Model: HH-FFAP
Application: GBZ/T 300.38-2017 Determination of Toxic Substances in Workplace Air Part 38: Carbon Disulfide

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has studied the determination of trace amounts of carbon disulfide in the atmosphere in HH-FFAP stationary liquid with flame photometric detector and the selection of carbon disulfide enrichment and desorption conditions. With carbon molecular sieve as the adsorbent, the best collection speed is 20 ml/min, the volume of desorption liquid is 15 ml, and the desorption time is 35 min. The external standard method was used for quantification, the recovery rate was 99.2%, and the lowest detected concentration was 2.0 4×10-8g/
