Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a headspace gas chromatography method for the determination of trimethylamine in waste gas from stationary pollution sources. The waste gas from the fixed pollution source is collected with weak acidic salt sun absorption solution. The absorption solution is transferred to a headspace bottle, and sodium hydroxide and ammonia shui are added. The content of trimethylamine in the waste gas from the fixed pollution source is determined by the hydrogen flame ionization detector of headspace gas chromatograph. The addition amount, equilibrium temperature and equilibrium time of capillary column, sodium chloride, potassium sulfate, hydrogen oxygen hua and ammonia shui are optimized. The experimental results show that when the absorption solution is 50.0 mL and the sampling volume is 20 L, the detection limit of trimethylamine is 0.010 mg/m3, the linearity is good, the correlation coefficient is 0.9998, the spiking recovery is 100.0%~107.0%, and the relative standard deviation is less than 5.0%.
