Influence of selected factors on performance of amperometric glucose biosensor

Effects of different ways of sample feed to the sensor, types of used membranes, extent of stretching the membrane pack by working electrode and timing of excitation voltage on performance of amperometric glucose biosensor with oxygen indicating electrode were investigated. In the sensors, enzymatic membranes containing immobilised glucose oxidase and some auxiliary membranes constituted an easily detachable laminated pack. In one of the tested sensors position of the membrane pack with respect to working electrode was adjustable. It was found that the above factors, except the timing of excitation voltage, have not essential influence on performance of O-2 - type glucose biosensor.
