An ion exchange membrane separated two electrode flow analyzer for continuous aqueous electrochemical heavy metal detection is disclosed. The electrochemical cell includes a gas diffusion counter/reference electrode, a flooded flow through working electrode, and an ion exchange membrane that separates the gas diffusion counter/reference electrode and the flooded flow through working electrode. A method of continuous fluid analysis using a multi-electrode flow analyzer is also disclosed, including passing an aqueous sample through a first inlet flow area and into a working electrode of a multi-electrode flow analyzer, passing a gas mixture through a second inlet flow area and into a counter/reference electrode of the multi-electrode flow analyzer, depositing an analyte onto a surface of the working electrode, stripping the analyte from the surface of the working electrode by sweeping a range of a potential applied to the surface of the working electrode.
