The Application of an Enzyme Electrode for Blood Glucose Determination in the Automated Flow System

Abstract
An enzyme electrode containing immobilized GOD was utilized in a continuous flow system for the automatical determination of glucose. The advantages of kinetic measurement of H2 O 2 are used. Characteristic parameters of device and results in routine are shown. Particular advantages are: low requirement on material (20 μl blood, < l μg GOD/measurement) and time (60 samples/h at 15 sec response time) as well as sufficient precision and accuracy (S % - serial: < 2 %).
