Abstract
A method of detecting the charged particles in an aqueous solution, including immersing one of two electrodes in the aqueous solution to provide a conductive path between the aqueous solution and the other electrode; applying a stepping potential through the electrodes to measure an impulse current through the aqueous solution; and comparing the measured impulse current with an impulse current of a reference solution having known ingredients to determine if the two solutions are similar.
