A method was developed for the determination of sucralose in soft drink by liquid chromatography ( LC) tandem a charged aerosol detector( CAD) with post column compensation. The results showed that the linearity was good and the correlation coefficient was above 0 . 999 . The limit of quantitation of the method was 1. 0 mg/L, and the recoveries of spiked samples were 97. 6%-112%. The method was simple and accurate, and can be used for the determination of sucralose in soft drink.
