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.
通过反相离子对色谱法可轻松测定软饮料中的奎宁。无需进行样品制备。通过连续监测柱流出物，采用荧光和紫外分光光度法检测奎宁。在20 - 100毫克/升的浓度范围内可获得线性响应。完整的分析过程大约需要8分钟。
