非抑制电导阳离子色谱法测定啤酒中的阳离子和胺类化合物

Determination of amine compounds and inorganic cations in beer by ion chromatography with non-suppressed conductivity detector

建立了以甲基磺酸（MSA）和乙腈混合淋洗，离子交换色谱分离．非抑制电导检测，分析分离啤酒中阳离子和胺类化合物的方法．色谱条件经优化．在25min内分离出啤酒中的7种阳离子和胺类化合物，方法的回收率和相对标准偏差分别为94．31％～109．9％和0．10％～1．2％．

An ion chromatography method with non-suppressed conductivity detection was developed for simultaneous determination of amine compounds and inorganic cations in beer by using MSA/acetonitrile as eluents. The results indicated that 7 kinds of amine compounds and inorganic cations in beer were separated in 25 rain. The method is simple and rapid. The recoveries and relative standard deviations are 94.31%- 109.90% and 0.10%- 1.2%, respectively.
