ELECTROCHEMICAL MEASUREMENT DEVICE

摘要

A flow cell for electrochemical measurement which introduces a sample solution, applies a voltage between a working electrode and a counter electrode to analyze the sample solution electrochemically, discharges the sample solution, and performs the electrochemical measurement continuously. The flow cell includes a unit which measures a value of a current flowing between electrodes at the time of applying a voltage, a unit which records the measured current value, a unit which compares the recorded current value with a current value set separately as a determination standard, and a unit which determines whether the current value measured at a cycle of a determination target and the recorded current value is normal by the comparison.

1. An electrochemical measurement device using a flow cell for electrochemical measurement which introduces a sample solution, applies a voltage between a working electrode and a counter electrode to analyze the sample solution electrochemically, discharges the sample solution, and performs the electrochemical measurement continuously, the electrochemical measurement device comprising:
a control device including:
a current measurement unit which measures a value of a current flowing between electrodes at the time of applying a voltage;a storage unit which records the measured current value;a comparison unit which compares a current value measured at a cycle of a measurement target with a determination standard based on a current value obtained at a cycle before the cycle and stored in the storage unit; anda determination unit which determines whether the current value measured at the cycle of the measurement target is normal by the comparison unit; and a communication device which, when it is determined that the measured current value is not normal, communicates abnormality of the current value to an operator.
