Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a method for the determination of vinyl chloride in workplace, ambient air and waste gas by thermal desorption and gas chromatography. Methods Carboxen1000 adsorption tube was used to adsorb vinyl chloride and dichloroethane in the workplace and ambient air, and then pyrolysis and gas chromatography were used for qualitative and quantitative analysis. Results The correlation coefficient of the standard curve reached 0.9998, the detection limit was 30ng/sample, the low detection concentration of zui was 0.02mg/m3 (calculated by collecting 1.5L air), the desorption efficiency was 91.3% - 94.5%, and the precision was 0.9% - 2.7%. After the adsorption tube was purified and the sample was collected, it was sealed with brass nuts and put into a sealed plastic bag for one week at room temperature. Conclusion: This method can be used for the determination of vinyl chloride in workplace, ambient air, exhaust gas and indoor air.
