Determination of Toxic Substances in Workplace Air Sulfide CS2
Determination of Toxic Substances in Workplace Air Sulfide CS2 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

In order to explore the actual carbon disulfide (CS2) exposure level of Chinese viscose workers and the representativeness of existing monitoring methods, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. applied an internationally unified sampling and analysis method to a viscose filament workshop The concentration of CS2 in the air in the workshop and the exposure level of CS2 workers were measured, and the representativeness of the three monitoring methods for measuring the workplace was evaluated. As a result, it was found that the sampling pump activated carbon absorber tube was used for sampling and analyzed by gas chromatography The concentration of CS2 at a fixed point in the workshop detected by the method is: 2 3.2 9± 1.35 mg/m3, the measurement result of the multi-function gas analyzer is 12.73 mg/m3, and the actual exposure level of the worker measured by the individual sampling method is: 20.0 5 mg/m3. Therefore, it is believed that it is not appropriate to replace the actual exposure level of workers with the commonly used air concentration in the workshop, because the difference between the two is statistically significant (P<0.01); it is recommended that the actual exposure level of workers should be the individual sampling method The measured result may be expressed as a time-weighted average concentration.
