摘要

In this work an automated flow methodology based oil a tubular amperometric detector coupled to a multi-commutated flow system was developed and applied in the determination of uric acid in urine. The exploitation of the analytical potential of multicommutated flow systems allowed the implementation of an expeditious and easily controlled on-line sample dilution, based oil the zone sampling approach. The dilution capability exhibited by the developed methodology allowed a direct insertion of the samples in the now system, without any pretreatment. assuring faster, simpler and less expensive analyses when compared to the enzymatic based methods with spectrophotometric detection commonly used in clinical analyses.
