Determination of Trimethylamine in Waste Gas of Stationary Pollution Source by Capillary Column Top Air Chromatography with HH-Tamine30 Methylamine
Determination of trimethylamine in waste gas of stationary pollution source by capillary column top air chromatography dedicated to HH-Tamine30 methylamine Details:
Name: HH-Tamine30 capillary column
Specification: 30m * 0.32mm * 5.0um
Operating temperature: 280 ° C
No.: 20220923001
Application: Determination of trimethylamine in waste gas of stationary pollution source by headspace gas chromatography
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 weak sun hydrochloric acid absorption solution is used to collect the waste gas from the fixed pollution source, the absorption solution is transferred to a headspace bottle, sodium hydroxide and ammonia are added, and the content of trimethylamine in the waste gas from the fixed pollution source is determined by the headspace gas chromatograph hydrogen flame ionization detector, and the addition amount, equilibrium temperature and equilibrium time of capillary column, sodium chloride, potassium sulfate, sodium hydrogen yangide, 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%.
