Abstract
A cell culture analysis device comprises a voltage application unit, a current measurement unit, a voltage measurement unit, and an analysis unit. The voltage application unit applies voltage to a sensing unit, which includes a working electrode, a counter electrode, and a reference electrode, of a sensor in a state in which the sensing unit is immersed in the culture medium. The current measurement unit measures the current flowing through the sensor from the voltage applied to the sensing unit. The analysis unit calculates the concentration of glucose or the like contained in a culture medium based on the measurement result. The voltage measurement unit measures the terminal voltage of the counter electrode in a state in which the voltage application unit is applying voltage. The analysis unit detects a measurement error based on the terminal voltage of the counter electrode.
