Determination of vinyl chloride in air by gas chromatography
Determination of vinyl chloride in the air by gas chromatography Details:

Name: Packed column

Stationary phase: organic support

Particle size: 80-100 mesh, 60-80 mesh

Specifications: 2m * 4mm, 2m * 3mm, 2m * 1 * 8

Model: 407 organic support, GDX-407
Application: Adsorption-automatic thermal analysis method for the determination of vinyl chloride in polluted air of factories

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. established a method for thermal desorption-gas chromatography determination of vinyl chloride in workplaces, ambient air, and exhaust gas. Method: Carboxen1000 adsorption tube was used to adsorb vinyl chloride and ethylene dichloride in the workplace and in the ambient air, and was qualitatively and quantitatively analyzed by thermal desorption-gas chromatography. Results: The correlation coefficient of the standard curve reached 0.9998, the detection limit was 30 ng / sample, and the lowest detection concentration was 0.02 mg / m. (According to the collection of 1.5L of air), the desorption efficiency is 91.3% ～ 94.5%, the precision is 0.6% ～ 4.2%, after the adsorption tube is cleaned and the sample is collected, it is sealed with brass nut It can be stored in a sealed plastic bag at room temperature for one week. Conclusion: This method can be used to detect the concentration of vinyl chloride in the workplace, ambient air, exhaust gas, and indoor air.
