Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a 4% PEG-20M+1% KOH/GDX-401 hard glass column to determine the content of trimethylamine. The column and solid adsorbent were treated with alkali to reduce adsorption, which is the characteristic of this method. The detection limit for trimethylamine is 5 35 μg/ml; The relative standard deviation is expressed as 4.5% to 6.2% for measuring precision; The desorption efficiency ranges from 95.9% to 99.4%; The determination of trimethylamine in the air has high sensitivity, good reproducibility, and is simple and easy to implement.
