Abstract
A measuring apparatus for measuring a substrate concentration by using a sensor including an enzyme reagent layer includes a state detecting unit that applies a first voltage and a second voltage different from the first voltage to the sensor to detect a state of the enzyme reagent layer based on a difference between a first response current value obtained under application of the first voltage and a second response current value obtained under application of the second voltage.

A measuring apparatus for measuring a substrate concentration by using a sensor including an enzyme reagent layer, comprising:
- a state detecting unit configured to a first voltage and a second voltage different from the first voltage to the sensor to detect a state of the enzyme reagent layer based on a difference between a first response current value obtained under application of the first voltage and a second response current value obtained under application of the second voltage.
A detection method for detecting a state of an enzyme reagent layer provided in a sensor, comprising:
- applying a first voltage to the sensor to measure a response current value of the sensor in response to the first voltage;
- applying a second voltage different from the first voltage to the sensor to measure a response current value of the sensor in response to the second voltage;
- and
- detecting the state of the enzyme reagent layer based on a difference between the measured two response current values.
A measuring system, comprising:
- a measuring apparatus that applies a voltage to a sensor connected thereto to measure a substrate concentration based on a response current value obtained under application of the voltage;
- and
- an electrochemical sensor that is connected to the measuring apparatus, and includes an enzyme reagent layer, and a plurality of electrodes to which a first voltage and a second voltage are applied in order that the measuring apparatus detects a state of the enzyme reagent layer based on a difference between a first response current value obtained under application of the first voltage and a second response current value obtained under application of the second voltage different from the first voltage.
