Abstract
A filter contamination measuring device includes: a working electrode adjacent to a first surface of a filter, the filter configured to adsorb an ionic material of a first polarity, a counter electrode disposed on the other surface of the filter, a potentiostat configured to apply a voltage of a second polarity to the working electrode for a predetermined period of time, and to measure current output from the working electrode. The potentiostat is configured to increase the voltage over the predetermined amount of time. The filter contamination measuring device further includes a controller configured to calculate a maximum current attained during the predetermined amount of time and a corresponding voltage value, and to determine the type and concentration of the ionic material based on the maximum current and the voltage value.
