Alkylamine is an important raw material for organic synthesis. The separation of lower grade aliphatic amines is carried out by using large diameter capillary column and the detection of nitrogen and phosphorus detectors (NPD). The headspace sampling method is used to determine low levels of aliphatic amines in water Higher. For the factory emissions of low-grade fatty acid in the determination of rare domestic reports.

    Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, Institute of Chromatography, analysis and testing center, three scientific research units , The analytical method of type II amine column dedicated capillary column was used to determine the separation of mono-, di- and trimethylamine and methanol in wastewater. The separation of each component was better, the water sample was not treated, the direct standard was measured and the relative standard deviation 6. 4%, the method meets the requirements of environmental monitoring.
