Determination of Monomethylamine/Dimethylamine in Workplace Air by Solvent Desorption Gas Chromatography
Solvent Desorption Gas Chromatography Determination of Monomethylamine/Dimethylamine in Workplace Air Details:
Name: capillary column
Statio nary Phase: Dedicated
Specifications: 20m*0.32mm*0.45um
Model: HH-Volamine
Application: Determination of Toxic Substances in Workplace Air Part 227: Mo nomethylamine and Dimethylamine
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a standardized method for the determination of mo nomethylamine and dimethylamine in workplace air by solvent desorption gas chromatography. Methods Silica gel tube was used to adsorb dimethylamine in the air, decomposed with acidic alcohol solution and neutralized by strong alkali, then injected into gas chromatography, separated by a basic chromatography column with high liquid loading ratio, and determined by FID detector. Results The linear equation of this method was Y=1040.2X-25148(r=0.9999) when the measurement range was 79.7~78.2μg/mL. The minimum detection limit is 5μg/ml; the minimum detection co ncentration is 1.3mg/m3 (ba sed on the collection of 7.5L air samples); the analytical efficiency is ≧86%; the breakthrough capacity (BTV) is greater than 7.75mg (200mg silica gel); the sample is at 4 It can be stored in the refrigerator for 7 days. Co nclusion The method established in this study is suitable for mo nitoring the co ncentration of dimethylamine in workplace air.
