甲胺、二甲胺、三甲胺均为无色有氨味的气体 ,它们是生产染料、药物、有机氮农药、表面活性剂及硫化促进剂的主要原料。它们均为中等毒性有机物 ,在生产上述产品的化工企业的排放废气及废水中常可检出。我国规定空气中甲胺的允许浓度为 5mg/m3 ,二甲胺为 1 0 mg/m3 。

滕州市浩瀚色谱仪器技术服务有限公司，与时俱进，以科学发展为指导，在王晓莹经理的带领下，依托翔鹰分析技术研究所，色谱工程研究所，分析与测试中心，3个科研单位，研发出HH-AMIV甲胺类分析*填充柱，分离了甲胺、二甲胺、三甲胺，结果满意。实用新型与现有技术的色谱柱相比，该色谱柱克服了现有技术产品不易分离三甲胺中的微量二甲胺，不能分离二甲胺中的微量三甲胺的缺陷。

Methylamine, dimethylamine, trimethylamine are colorless ammonia smell of the gas, they are the production of dyes, drugs, organic nitrogen pesticides, surfactants and curing agent of the main raw materials. They are medium toxic organic matter, in the production of these products, chemical industry emissions and waste water can often be detected. China provides the air to allow the concentration of methylamine 5mg / m3, dimethylamine 10 mg / m3.
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 Analysis Technology Research Institute, Institute of Chromatography, Analysis and Testing Center, three scientific research units , Developed HH-AMIV methylamine analysis dedicated packed column, the separation of methylamine, dimethylamine, trimethylamine, the results were satisfactory. Compared with the prior art, the utility model can not separate the trace amount of dimethylamine from trimethylamine in the prior art product, and can not separate the trace amount of trimethylamine in dimethylamine. The following are the same as those of the "
