Abstract
An embodiment provides a method for measuring a component of an aqueous sample using square wave modulation, including: introducing the aqueous sample to a chamber of a square wave modulation apparatus; applying a stimulus voltage step to the aqueous sample, wherein the stimulus voltage comprises a staircase voltage, wherein each step of the staircase voltage defines a group, wherein the group comprises one or more square wave modulation cycles; adjusting a time acquisition window, wherein the time acquisition window is a portion of each of the half cycle of the stimulus voltage; measuring a resultant current output resulting from the stimulus voltage within the time acquisition windows; and averaging the resultant current output across at least one or more cycles of each group. Other aspects are described and claimed.
