由于氨基存在，挥发性胺类溶剂与色谱柱以及样品流路活性位点相互作用，造成的宽峰和拖尾。

　　胺通常是在水、酒精或氨水的环境下进行分析的，基质苛刻，色谱柱耐受性易下降。

　　挥发性胺类沸点较低，相对保留较较弱。

　　Due to the presence of amino groups, volatile amine solvents interact with the chromatographic column and active sites in the sample flow path, resulting in broad peaks and tails.

　　Amines are usually analyzed in environments such as water, alcohol, or ammonia solution, with harsh matrices and decreased column tolerance.

　　Volatile amines have lower boiling points and relatively weaker retention.

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a HH-AMB amine analysis column specifically designed for the determination of dimethylamine, dimethylamine, and trimethylamine. The column has high efficiency, good separation, and short analysis time. It has been applied to Agilent, Shimadzu, Thermo Fisher Scientific, Varian, Bruker, PE, Panno, Tianrui, Tianmei, Kechuang, Chuanyi and other instruments with accurate quantification.
