A short gas-chromatographic method for analysing urinary concentrations of 2,5-hexanedione is based on acid hydrolysis of urine at pH below 0.1 and "purification" of the urine samples by microcolumns containing an octadecyl-silane phase. A 5% acetonitrile solution allows a fairly selective elution of 2,5-hexanedione from the microcolumns. Recovery of 2,5-hexanedione from urine is as great as 79.9%. The variation coefficient of the measurements is 2.8%. The results obtained from different working conditions and using packed or wide bore or capillary gas-chromatographic columns are reported.
一种用于分析尿中2,5 - 己二酮浓度的短程气相色谱法,其基于在pH值低于0.1的条件下对尿液进行酸水解,并通过含有十八烷基硅烷相的微柱对尿液样本进行“纯化”。5%的乙腈溶液可使2,5 - 己二酮从微柱中得到相当选择性的洗脱。尿中2,5 - 己二酮的回收率高达79.9%。测量的变异系数为2.8%。报告了在不同工作条件下以及使用填充柱、宽口径柱或毛细管气相色谱柱所获得的结果。
