Application: GBZ/T 160.60-2004 Determination of Toxic Substances in Workplace Air-Anhydride Compounds
GBZ/T 300.118-2017 Determination of Toxic Substances in Workplace Air Part 118: Acetic Anhydride, Maleic Anhydride and Phthalic Anhydride

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a method for the determination of phthalic anhydride solvent desorption gas chromatography in workplace air, which provides a certain reference for the future determination of phthalic anhydride. The use of phthalic anhydride in the collection Glass fiber filter paper, acetone is desorbed and separated by DM-5 capillary chromatographic column, detected by FID detector, and detected by phthalic anhydride solvent desorption gas chromatography. This method has high sensitivity and high average desorption efficiency. The relative standard deviation for the determination of diformic anhydride was between 2.7% and 3.4%.
