Determination of Vinyl Chloride in Air by Adsorption Thermal Desorption Gas Chromatography
Determination of Vinyl Chloride in Air by Adsorption Thermal Desorption Gas Chromatography Details:

Name: stainless steel column

Specifications: 1.2m*3mm

Model: GDX-105/80-100 mesh

Number: 20220719002

Temperature: 250°C

Application: HJ T 34-1999 Determination of Vinyl Chloride in Exhaust Gas from Stationary Pollution Sources Gas Chromatography

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a thermal desorption-gas chromatography method for the determination of vinyl chloride in workplaces, ambient air and waste gas. Methods: The Carboxen1000 adsorption tube was used for the qualitative and quantitative analysis of vinyl chloride and dichloroethane in the workplace and ambient air by thermal desorption-gas chromatography. Results: The correlation coefficient of the standard curve reached 0.9998, the detection limit was 30 ng/sample, the minimum detection concentration was 0.02 mg/m~3 (based on 1.5 L of air), the desorption efficiency was 91.3%~94.5%, and the precision was 0.6%~4.2 %, after the adsorption tube is cleaned and the sample is collected, it is sealed with a brass screw cap and placed in a sealed plastic bag for one week at room temperature. Conclusion: The method can be used to detect the concentration of vinyl chloride in workplace, ambient air, waste gas and indoor air.
