Abstract:
A flow-through electrochemical cell assembly comprising(a) a perimeter wall defining a sample flow channel including an inlet and an outlet, (b) a sample inlet line in fluid communication with said sample flow channel inlet, (c) a sample outlet line providing fluid communication between said sample flow channel outlet and a remote reference electrode, and (d) a disposable working electrode structure comprising an electrically conductive and electrochemically active working electrode region bound as a layer, directly or indirectly, to an electrically insulating substrate surface, said substrate surface being in fluid-sealing relationship with said sample flow channel, at least a portion of the substrate surface being exposed to the sample flow channel and said working electrode region being in fluid communication with said sample flow channel, said working electrode structure being removable from said electrochemical cell assembly.
