Abstract

In an electrochemical sensor, the potential difference applied to the electrochemical cell is raised to a measuring value at a rate determined to reduce the transient current. The maximum rate of change of the voltage is set to prevent saturation of an IE converter. The electrochemical cell may contain micro-electrodes as working and reference electrodes. The method may be applied to a battery powered, handheld device.
