| Abstract: | The differential pulse voltammetric oxidation of polyinosinic acid (poly(I)), inosine-5'-monophosphate, inosine and hypoxanthine at a pyrolytic graphite electrode has been studied. Poly(I) gives a single, pH-dependent voltammetric oxidation peak which is well separated from the single peak observed for very low concentrations of hypoxanthine. An electroanalytical method for the detection and determination of trace amounts of hypoxanthine in poly(I) samples is described. |
