Determination of vitamin C in urine by flow injection analysis
Abstract
A spectrophotometric method with flow injection analysis is described for the determination of vitamin C in urine, which presents substantial improvements over the existing conventional manual and automatic methods. Determinations can be carried out at the µg ml–1 level; the method has an average recovery error of ±2.5% and a sampling frequency of 90 samples h–1 can be attained.
