title: Rapid determination of quinine in soft drinks by reversed phase ion pair chromatography.
abstract: Quinine can easily be determined in soft drinks by means of reversed-phase ion-pair chromatography. Sample preparation is not necessary. Quinine is detected by fluorescence and UV spectrophotometry by continuous monitoring of the column effluent. A rectilinear response is obtained in the concentration range of 20--100 mg/l. The complete assay procedure takes about 8 min.
