A rapid method has been developed for the determination of sodium saccharin, caffeine, aspartame, and sodium benzoate in cola beverages. The sample is degassed, diluted in water, and injected onto a C18 column. The mobile phase consists of 15% acetonitrile in triethylammonium phosphate buffer adjusted to pH 4.3 with NaOH. The total run time is less than 10 min and the active compounds are determined using absorbance detection at 214 nm.
已开发出一种快速方法用于测定可乐饮料中的糖精钠、咖啡因、阿斯巴甜和苯甲酸钠。将样品脱气，用水稀释，然后注入C18柱。流动相由在磷酸三乙铵缓冲液中含15%乙腈组成，该缓冲液用NaOH调节至pH 4.3。总运行时间少于10分钟，使用214nm处的吸光度检测来测定活性化合物。
