Determination of trimethylamine in waste gas of stationary pollution source by headspace gas chromatography (nitrogen phosphorus detector)

Determination of trimethylamine in waste gas of fixed pollution source by headspace gas chromatography (nitrogen phosphorus detector) Details:



Name: HH-Tamine60 methylamine special capillary column

Specification: 60m * 0.32mm

*High service temperature: 280 ° C

No.: 20220109001



A headspace gas chromatography method for the determination of trimethylamine in waste gas from stationary pollution sources was established by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd The weak acid absorption solution is used to collect trimethylamine in the waste gas of fixed pollution source, neutralize the alkali solution, and then analyze it with headspace sampling gas chromatograph nitrogen and phosphorus detector The conditions of equilibrium temperature, equilibrium time, salting out effect, ammonia and sodium hydroxide were optimized. Under the best experimental conditions, the detection limit of trimethylamine method was 0.46 μ G/m3 (calculated by collecting 20 L air sample), the recovery rate of spiking is 97% ～ 107%, and the relative standard deviation is below 9.26% This method is used to detect and analyze trimethylamine in the air at the boundary of waste incineration power plant and in the organized waste gas of fish meal plant. This method can meet the requirements of national standards and local standards for emission limits of trimethylamine
