摘要：

The quantitative ability of the presented alkali flame ionization detector to determine the amount of caffeine in selected beverages is examined. A sample cleanup and concentration procedure is employed followed by gas chromatographic separation with alkali flame ionization detection. The amount of caffeine in 12-ounce containers of the beverages ranged from 35 mg to 60 mg. The linear response range of caffeine was observed to be 3.7 orders of magnitude. © 1993 Academic Press.
