[Determination of caffeine in teas by supercritical fluid chromatography].
摘要
A rapid supercritical fluid chromatographic method for the determination of caffeine in tea is described. It is shown that a mobile phase of carbon dioxide, modified with 5% methanol achieved excellent results. The method is simple in the sample preparation. Other components contained in the sample do not interfere the measurement. It can be used to determine caffeine in tea rapidly.
