Experimental conditions have been studied in order to improve the sensitivity for the analysis of diuretics and probenecid in urine samples by high-performance liquid chromatography with ultraviolet detection. Sample clean-up and chromatographic parameters have been optimized to obtain a suitable sensitivity for the detection or quantification of each diuretic using an HP-Hypersil ODS-C18 column (5 microns, 250 mm x 4 mm I.D.), taking into account the pharmacological properties of each compound. The reliability of this method was tested by analysing urine samples after a minimum single-dose administration of chlorthalidone and probenecid.
为了提高高效液相色谱-紫外检测法分析尿样中利尿剂和丙磺舒的灵敏度，对实验条件进行了研究。考虑到每种化合物的药理特性，已对样品净化和色谱参数进行了优化，以使用HP-Hypersil ODS-C18柱（5微米，250毫米×4毫米内径）获得检测或定量每种利尿剂的合适灵敏度。通过分析单次最小剂量服用氯噻酮和丙磺舒后的尿样，对该方法的可靠性进行了测试。
