| 摘要 | 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. | ||

| 主权项 | 1. A measuring apparatus for measuring a substrate concentration by using a sensor containing an enzyme reagent layer, the measuring apparatus comprising: a state detecting unit configured to apply 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, wherein the state detecting unit is further configured to detect that the enzyme reagent layer is in a degraded state when the difference between the first and the second response current values is equal to or greater than a threshold value when the second voltage is of a higher voltage than the first voltage. | ||
