摘要
参考GB/T5009.97-2003《食品中环己基氨基磺酸钠的测定》,对气相色谱分析方法进行优化改进,将U形不锈钢柱改为宽口径毛细管柱。加标回收率为98.7%～108.0%。该方法分离效能高、分析速度快、灵敏度高,溶剂峰和样品峰能很好地分离,检测结果更准确。
The method used in this paper refers to the GB/T 5009.97-2003 ＂of sodium cyclamate in foods determination＂ , the gas chromatography analysis method was improved, the U stainless steel column instead of wide bore capillary column. The standard addition recovery rate is 98.7% 108.0%. The method of high separation efficiency, fast analysis speed, high sensitivity, the solvent peak and the sample peak well separated, the detection result is more accurate. On 6 large supermarkets in the area and 15 individual stores collected 30 fruit samples were tested with the improved method, preserves the sample pass rate of 83.3%.
