Determination of Acetic Anhydride in the Air of Workshop by Chromatography
Determination of Acetic Anhydride in the Air of Workshop by Chromatography

Name: Packed column

Stationary phase: porous polymer support of 2,6-diphenyl-p-phenylene ether

Specification: 2m*4mm

Material: glass column/stainless steel

Model: Tenax

Application: GBZ/T 300.118-2017 Determination of Toxic Substances in Workplace Air Part 118: Acetic Anhydride, Maleic Anhydride and Phthalic Anhydride



The chromatographic method simultaneously determines the acetic acid and acetic anhydride in the air of the workshop and the application of the monitoring data on the computer. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses activated carbon tube for sampling, acetone desorption, acetic acid and acetic anhydride separated by gas chromatography, qualitative by retention time, peak separation quantification, and the monitoring data of the standard curve can be processed directly by the data processor Sample injection instead of checking the standard curve. Chromatographic method is used to determine the workshop at the same time.
