Gas Chromatographic Determination of Vinyl Chloride in Workplace Air
Gas Chromatographic Determination of Vinyl Chloride in Workplace Air Details:

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a solvent-desorption gas chromatography method for the determination of vinyl chloride in workplace air. [Method] Sampling by activated carbon tube, desorption of carbon disulfide, separation by GDX-105 column, detection by hydrogen flame ionization detector. [Result] The sampling efficiency was over 90% with activated carbon tube at the speed of 0.2 L/min for 10 min; the method had good reproducibility, the relative standard deviation of different concentrations was 1.98%-5.83%; the average desorption efficiency was 93.7%, and the determination The range is 7.5-120.0 mg/m3; the minimum detectable concentration is 1.5 mg/m3 (sampling 2 L); the penetration capacity is 0.47 mg (100 mg activated carbon). [Conclusion] The indicators of this method all meet the requirements of the research specification of "Workshop Air Monitoring and Inspection Method", and it is suitable for on-site monitoring of vinyl chloride in the workplace air.
