چکیده

An automated procedure is presented for the enzymatic determination of serum uric acid on both the AutoAnalyzer and the Robot Chemist. The procedure measures as the neocuproine complex, the difference in the amount of Cu+ formed by reaction of a Cu++ aIkanoIamine buffered solution with serum uric acid under precisely controlled conditions before and after uricase treatment of the serum. The difference is proportional to the true serum uric acid content. The elements contributing to the enzymatic reaction, the colorimetric reaction, and the elimination of interferences were investigated. Comparison of serum uric acid values obtained by this method with those obtained by ultraviolet spectrophotometry show very good agreement.

Simultaneous determination of dopamine and uric acid using a glassy carbon paste electrode modified with copper- para red complex

A simple approach based on cyclic voltammetry (CV) was developed for the simultaneous determination of dopamine (DA) and uric acid (UA) in the presence of ascorbic acid (AA) using a modified glassy carbon paste electrode (GCPE). In the present study, analytical parameters were optimized and electrochemical performance of modified electrode was investigated. The calibration curves were obtained ...

A new automated determination of uric acid.

A new method for the automated determination of uric acid in serum and urine, using the Auto Analyzersystem, is reported. This method is based on the colour reaction of uric acid with phosphotungstic acid in an alkaline solution. The results obtained by this method are satisfactory and reliable. It is considered that the method can be useful as a routine test for uric acid in clinical laborator...

Determination of Uric Acid: an Automated Analysis Based on a Carbonate Method.

VARIETY of methods is available for tue colorimetric determination of uric acid. In general, these are based on precipitation of proteins, followed by the reduction in an alkaline medium of phosphotungstate by the uric acid ill the protein-free filtrate. Results of colorimetric determinations may at times vary from “true” uric acid values as determined by unease methods. This is because the col...
