Determination of urinary phenol by acid hydrolysis and capillary gas chromatography.
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%.
