@@@@An analytical method for fast determination for sodium cyclamate in red dates by gas chromatography was developed. The sodium cyclamate in red dates was separated by Rtx-WAS column, and determined by a fire iron detector (FID). The result showed that the linear range was between 0.1 mg/mL-10.0 mg/mL and the linear correlation coefficient was 0.999 6. The detection limit was 0.003 g/kg, and the average recoveries were between 87.6%and 108.8%with the relative standard deviations (RSDs) of 2.9%-5.3%(n=5). It was proved to be a convenient and accurate method for the analysis of sodium cyclamate in red dates.
