Determination of epichlorohydrin in workplace air by gas chromatography
Determination of Epichlorohydrin in Workplace Air by Gas Chromatography Details:

Name: capillary column
Specifications: 30m*0.32mm*0.5um
Model: HH-FFAP
Application: Determination of Toxic Substances in Workplace Air Part 58: Ethylene Oxide, Propylene Oxide and Epichlorohydrin

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a new method for the determination of epichlorohydrin in workplace air. Methods: Epichlorohydrin in air was collected by activated carbon tube, desorbed by carbon disulfide, separated by HH-FFAP column, and detected by hydrogen flame ionization detector. Results: The minimum detection limit of the method was 0.35μg/ml, the minimum detection concentration was 0.12 mg/m3 (based on the collection of 3.0 L air sample), the linear range was 1.6~80μg/ml, the relative standard deviation was 0.13%~0.38%, The correlation coefficient is 0.9999. The average sampling efficiency was 94.8%, and the average desorption efficiency was 92.0%. CONCLUSION: The method is simple, sensitive and accurate, and is suitable for the determination of epichlorohydrin in workplace air.
