High pressure liquid chromatographic determination of sodium saccharin, sodium benzoate, and caffeine in soda beverages: collaborative study.
A collaborative study for the determination of sodium saccharin, sodium benzoate, and caffeine in 3 types of soda beverage, cola, grape, and lemon-lime, has been completed using reverse phase high pressure liquid chromatography with a muC18 column and acetic acid mobile phase. Recoveries for sodium saccharin were 98.6, 98.0, and 99.1%; for sodium benzoate, 100.6, 102.6, and 100.6%; and for caffeine, 100.8, 101.4, and 101.1%, respectively. The method has been adopted as official first action.
