ECD气相色谱或气质联用仪分析食品中环己基氨基磺酸钠的含量

本文研究了检测食品(如话梅、果冻、糖果及饮料等)中环己基氨基磺钠含量的方法，该方法快速简便，并得到气质联用仪的确证。环己基氨基磺钠在酸性条件下与亚硝酸钠反应生成环己基亚硝酸酯，ECD气相色谱能快速地有选择性地检测到该化合物，该法的检测出限为1．0mg／kg，线性范围为0．99914，回收率范围为70％～130％。

Determination of Cyclamate in Foods by Gas Chromatography with ECD or MSD

A rapid and simple gas chromatographic method for determination of cyclamate was developed in food samples such as plum, jelly, candy, beverage and so on. This method had been confirmed by gas chromatography with mass-selective detection. Cyclamate could react with sodium nitrite when vitriol existing and then produce cyclohexane nitrite, which could be extracted by hexane and can easily be detected in food samples with Agilent 6890 gas chromatography. This method was successfully applied to the analysis of several food samples and the recoveries for these samples ranged from 70%～ 130%. The linearity was 0.99914 and the limit of determination was 1.0mg/kg.
