Hipoxantina, xantina e ácido úrico são purinas encontradas em fluídos extracelulares, que podem ser utilizados como marcadores metabólicos, indicadores da idade de carnes e outras aplicações. Estudos voltamétricos foram desenvolvidos para investigar a possibilidade da determinação simultânea destes analitos em ultramicroeletrodos de fibra de carbono (diâmetro de 7 μm). Os estudos efetuados mostraram a possibilidade destas determinações com coeficientes médios de recuperação da ordem de 97,6%, ao nível de μmol L-1. Hypoxanthine, xanthine and uric acid are purines present in extracellular fluids that can be used as metabolic markers, in evaluation of meat conservation and other applications. Voltammetric stud- ies were performed in order to investigate the possibility of simultaneous determination of these compounds using carbon fiber ultramicroelectrodes (7 μm diameter). The studies revealed the possibility for performing such determinations with mean recoveries of 97.6% in mixtures of the three compounds at μmol L-1 level.
