　　The Haohan chromatography study used gas chromatography to determine the concentrations of dimethylamine, dimethylamine, and trimethylamine in industrial methylamine solutions, and also conducted experiments on interfering ions. The minimum detection limits for methylamine, dimethylamine, and trimethylamine in industrial methylamine solution determined by this method are 0.1, 0.3, and 0.8 mg/L, respectively. The relative standard deviations are 5.25%, 6.64%, and 7.13%, respectively. The recovery rates are between 90-104%, 91.4-95.7%, and 90-93.4%, respectively.

　　The development of HH-AM methylamine specific column for the determination of ammonia, dimethylamine, and trimethylamine content in methylamine solution by GC method using Haohan chromatography. By detecting impurities such as ammonia, dimethylamine, and trimethylamine in methylamine solution, and controlling the column type and parameters in gas chromatography, detector type and collection mode in mass spectrometry, and detection concentration of the test solution, it is possible to simultaneously detect ammonia, dimethylamine, and trimethylamine in methylamine solution with high sensitivity, accuracy, and specificity.
