ABSTRACT:
Disclosed are systems and methods that include a flow-cell that includes porous conductive material(s) that provides a working electrode(s), an inlet connected to the flow-cell to deliver a solution continuing an analyte(s), an outlet connected to the flow-cell to allow the solution to exit the flow-cell, a counter electrode positioned proximate to the outlet, and a voltage source(s) coupled to the working electrode(s) and the counter electrode. The methods can include delivering a solution containing an analyte(s) through an inlet to a flow-cell that includes porous conductive material(s) that provides a working electrode(s), connecting the flow-cell to an outlet for allowing the solution to exit the flow-cell, placing a counter-electrode proximate the outlet, and supplying a voltage from a voltage source(s) to the working electrode(s) and/or the counter-electrode.
