Abstract
A fully automated method has been developed to determine total phenol in urine. Results agree well with the accepted manual method. In this automated method, samples are run at the rate of ten per hour. Only 1 to 2 ml of sample is needed. In 1 man-day, forty samples can be analyzed. To utilize the automated equipment efficiently, larger sample loads can be obtained by storing the samples in screw-cap vials. No phenol losses occur in 2 weeks’ storage.
