Glucose-oxidase electrode. Measurements of glucose in samples exhibiting high variability in oxygen content

Measurements of glucose in samples exhibiting high variability in oxygen content present an important problem to solve for pO2 detection methods. Different solutions exist, all based on the stabilization of the pO2 sample before or during the measurement. The electrode described in this paper itself contains enough O2 to compensate for the variability of the sample oxygen content. The enzyme is cross-linked with gelatin using the bifunctional agent, glutaraldehyde. Amperometric enzyme electrodes have been constructed using these membranes. Measurements have been done by collecting the derivative in time of the signal given by the electrode for blood or plasma samples.
