Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses GB/T14676-93 "Determination of Trimethylamine in Air Quality - Gas Chromatography Method" to determine trimethylamine in the air. Through experiments, the analysis conditions are determined, and 1mL of sample gas is directly injected. The relative standard deviation of the analysis results is less than 3%, the recovery rate is greater than 98%, and the detection limit reaches 0.0028mg/m3, which meets the requirements of monitoring and analysis technology This method is applicable for the determination of trimethylamine in the exhaust gas of odor pollution sources and the ambient air of factories It has advantages such as high sensitivity and easy operation
This standard is applicable to the determination of trimethylamine in the exhaust gas of odor pollution sources and the ambient air of factories. When the sampling volume is 10L, the minimum detectable concentration of the method is 2.5-3 × 10mg/m3. This standard determines the presence of trimethylamine in a gaseous state. The amine compounds such as ammonia, methylamine, ethylamine, and dimethylamine in the sample do not interfere with the determination of trimethylamine under the chromatographic conditions selected in this method.
