甲胺、二甲胺、三甲胺均為無色有氨味的氣體 ,它們是生產染料、藥物、有機氮農藥、表面活性劑及硫化促進劑的主要原料。它們均為中等毒性有機物 ,在生產上述產品的化工企業的排放廢氣及廢水中常可檢出。我國規定空氣中甲胺的允許濃度為 5mg/m3 ,二甲胺為 1 0 mg/m3 。

     滕州市浩瀚色譜儀器技術服務有限公司，與時俱進，以科學發展為指導，在王曉瑩經理的帶領下，依托翔鷹分析技術研究所，色譜工程研究所，分析與測試中心，3個科研單位，研發出HH-AMIV甲胺類分析填充柱，分離了甲胺、二甲胺、三甲胺，結果滿意。實用與現有技術的色譜柱相比，該色譜柱克服了現有技術產品不易分離三甲胺中的微量二甲胺，不能分離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 "
