Abstract

The development of needle electrodes has allowed the measurement of various parameters in the tissue of different organs such as nervous activity, microflow, ion activities, and oxygen partial pressure. To investigate the interdependence and mutual influence of these parameters, simultaneous recorders with multichannel electrodes may be used. Different methods have been employed to use one of the channels for the Polarographic measurements of oxygen or hydrogen. Silver (1976) centrifuges an organic liquid compound of palladium and gold into the channel. Tsacopoulos and Lehmenkühler (in press) introduce an etched platinum wire into the channel of the microelectrodes and fix it with wax. In the following report we would like to present a further method that allows the use of one channel of a 2 channel glass electrode for Polarographic measurement.
