Application: Determination of Toxic Substances in Workplace Air Part 227: Monomethylamine and Dimethylamine

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied a method for the rapid separation and determination of monomethylamine, dimethylamine and trimethylamine in ambient air by using a glass packed column of gas chromatography. The results show that the use of FID detector, external standard method Direct injection, the standard curves of monomethylamine, dimethylamine and trimethylamine have good linearity, and the correlation coefficients reach 0.998 3, 0.997 5, 0.996 6, respectively; the minimum detectable mass concentrations of monomethylamine, dimethylamine and trimethylamine in the air They are 17, 29, and 24 ng/L, respectively, which can meet the requirements for the determination of organic amines in ambient air.
