Voltammetric flow-injection determination of glucose in blood serum

Abstract

A method for voltammetric flow-injection determination of glucose in blood serum is described by which the catalytic current associated with formation of the Fehling reactant on a metallic copper electrode is used as the analyte signal. The analyte signal is proportional to the concentration of glucose in the range of 1 × 10-4 - 1 × 10-3 M, and the throughput of the FIA system is 50 samples/h. The detection limit for determination of glucose is found to be 2 μg/ml. © 1999 Plenum Publishing Corporation.
