Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses a 4% PEG-20M+1% KOH/GDX-401 glass column to collect trimethylamine from unorganized waste gas using weakly acidic absorption solution. After adding alkaline solution, the trimethylamine in the absorption solution escapes to the upper space at a certain temperature and reaches dynamic equilibrium in the gas-liquid phase after a certain period of time. Use a hydrogen flame ionization detector to determine trimethylamine in the gas phase. The experimental results showed that when the volume of the unorganized exhaust gas absorption solution was 9.9 mL and the sampling volume was 19 L, the detection limit of trimethylamine was 0.0032 mg/m3, with good linearity and a correlation coefficient of 0.9998. The spiked recovery rate was 93.0% -99.99%.
This standard specifies the gas chromatography method for the determination of trimethylamine in organized and unorganized emissions from environmental air and odor fixed pollution sources.
This standard is applicable to the determination of trimethylamine in organized and unorganized emissions from environmental air and odor fixed pollution sources. When the sampling volume is 10L, the method Zuidi determines a concentration of 2.5 × 10-3mg/m3.
