Abstract
Abstract To assay maltose to quantitatively determine amylase, there is used a sensor having an enzyme membrane having immobilized a-glucosidase and glucose oxidase and an enzyme electrode. To provide a stable maltose sensor with a long life and high sensitivity, the sensor has an enzyme electrode (1-5) which is a hydrogen peroxide electrode provided with a palladium cathode (5).
