    • It is intended to provide a sensor chip that enables detection of a deterioration state of a reagent applied on a reaction portion when measuring a concentration of a measurement object substance and a sensor system that enables a correct measurement by using the sensor chip for detecting the reagent deterioration state. A sensor chip including two substrates opposed to each other, a spacer layer sandwiched between the substrates, a multiple reaction portions provided in the spacer layer, and detection electrode units disposed on surfaces of the substrates facing to the spacer layer and exposed to the reaction portions, wherein an identical reagent A is applied on two or more of the reaction portions, and another reagent B that reacts with the reagent A is applied on at least one of the two reaction portions and a sensor system including the sensor chip and a measurement unit for comparing current values from the two or more reaction portions on which the identical reagent A is applied.
    • 本发明旨在提供一种传感器芯片,其能够检测在测量对象物质的浓度的反应部分上施加的试剂的劣化状态,以及能够通过使用用于检测试剂的传感器芯片进行正确测量的传感器系统 劣化状态。 一种传感器芯片,包括彼此相对的两个基板,夹在基板之间的间隔层,设置在间隔层中的多个反作用部分和设置在面向间隔层的基板的表面上并暴露于反应部分的检测电极单元 其中相同的试剂A施加在两个或更多个反应部分上,另一个与试剂A反应的试剂B施加在两个反应部分中的至少一个上,以及包括传感器芯片和测量单元的传感器系统 用于比较来自施加相同试剂A的两个或更多个反应部分的电流值。
