Acetic anhydride air monitoring packed column
Acetic anhydride air monitoring packed column Details:

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

 


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. conducted a standardized study on the gas chromatography determination method of acetic anhydride in the air. In addition, an occupational hygiene investigation was carried out on the acetic anhydride workshop of a certain factory, and the places where workers often stay in the acetic anhydride production workshop were sampled twice in 2 years and analyzed by gas chromatography. The average concentration of acetic anhydride in the air of the finished product packaging and the pump room was 2 3.1 mg/m3 and 2 6.0 mg/m3, respectively, and the concentration range was 1 9.6-31.5 mg/m3. Workers had dry eyes and burning eyes. The incidence of symptoms such as tearing and tearing was significantly higher than that of the control group and other workers.
