✦ Synopsis
A gas chromatographic method has been developed for the determination of caffeine in plasma. A standard response curve relating signal-height ratios of caffeine to hexobarbital permits a quantitative estimation of the amount of caffeine present. The method is more rapid and sensitive than any previously reported. Plasma levels of caffeine after the ingestion of one cup of coffee have been studied and concentrations down to 0.25 mcg./ml. have been accurately determined.
