An improved method for the determination of urinary phenol by the traditional precolumn hydrolysis technique is described. Following acid hydrolysis and diethylether extraction, phenol is separated from other urinary components within 3 minutes using the proposed capillary GC method. Analytical recovery was over 95%. The within-run CV was less than 2% and the day-to-day variation was less than 8%.
本文描述了一种通过传统的柱前水解技术测定尿酚的改进方法。经过酸水解和乙醚萃取后，使用所提出的毛细管气相色谱法可在3分钟内将酚与其他尿液成分分离。分析回收率超过95%。批内变异系数小于2%，日间变异小于8%。
