Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., in accordance with the relevant provisions of HJ/T55 or GB/T16157, absorbs and collects trimethylamine from fixed pollution source exhaust gas using a fixed amount of 0.12mol · L ^ -1 hydrochloric acid solution. Take 10.00mL of sample solution and transfer it to a headspace vial. Add 3.2g of sodium chloride and 1.0g of potassium sulfate, and use a microsyringe to add 500 μ L of 50% NaOH solution and 100 μ L of ammonia solution. Immediately seal the headspace vial and perform headspace sampling under the conditions of headspace equilibrium temperature of 80 ℃ and equilibrium time of 30 minutes. The HH-Tamin60 dedicated quartz capillary chromatography column was selected for quantitative separation of trimethylamine and five other fatty amine compounds studied, and hydrogen flame ionization detector (FID) was used for detection. Take 20L of trimethylamine standard gas according to the methods specified in HJ/T55 and GB/T16157, and conduct 7 parallel tests. The detection limit [tn-1,0.99) × s] of the previous sampling method was 0.004mg · m ^ -3, and the detection limit [tn-1,0.99) × s] of the latter sampling method was 0.02mg · m ^ -3. Three different concentrations of trimethylamine standard gas, namely high concentration (0.510 μ mol · mol ^ -1), medium concentration (0.102 μ mol · mol ^ -1), and low concentration (0.0102 μ mol · mol ^ -1), were taken and analyzed six times according to the prescribed method. The recovery rate of trimethylamine was calculated to be between 90.1% and 108%, and the relative standard deviation of the measured values (n=6) was between 2.2% and 6.7%. The application of this method to analyze actual samples shows that the method can meet the national standard GB14554-93 and the regulations on the emission of odorous pollutants, and cooperate with the implementation of the above standards.
