Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a method for determining phthalic anhydride in workplace air
Phthalic anhydride in the air was collected using glass fiber filter paper, and then placed into a sample bottle pre filled with 2 ml of acetone. The bottle was capped and shaken well. Then, a 2m × 4mm mixture of polyethylene succinate: phosphoric acid: 101 silanized white support was used, with a ratio of 5:1.5:100; Column gas chromatography (FID) determination. The linear relationship of phthalic anhydride concentration is good within the range of 0-210 μ g/ml, and the linear equation is y=8.95+12.8x (r=0.999 8).
