摘要
目的 研究环已基磺酸钠在不同溶剂中毛细管柱中的色谱行为 ,探索用不同的色谱条件测定环已基磺酸钠的最佳分析结果。方法 采用氢火焰—气相色谱法 (FID -GC)。结果 在最佳条件下结果显示在0 .4～ 1.2mg/ml范围内呈良好的线性关系 (r =0 .9993) ,3份样品测定 6次其相对标准偏差为RSD(% )为 3.1、2 .2、3.9。方法的回收率 95 .4 %～ 10 0 .6 % ,检测限为 0 .2mg/kg。 结论 本法简单、快速、准确、易于操作 ,适用于果汁、蜜饯等食品中环乙基磺酸钠的测定。
Objective In order to study chromatography behavior in capillary column of different dissolvent for sodium cyclamate detection and explore optimum analysis results of sodium cyclamate in different chromatography condition. Methods The hydrogen ionization detector-gas chromatograph(FID-GC)was applied. Results The linear range and coefficient of liner correlation was 0.4～1.2mg/ml and 0.9993 respectively. The relative standard deviation of three simples was 3.1、2.2、3.9. The recovery of the method was 95.4%～100.6%. The detection limit was 0.2mg/kg. Conclusions The results showed that the method was simple, rapid, accurate and easy to operate. It could be applied for detection of sodium cyclamate in fruit syrup, confect and etc.
