Electrochemical Detector Working Electrodes for Thin Layer Flow Cells
BASi® working electrodes contain a cylinder of electrode material embedded in a PEEK block. The surface is polished to a mirror finish. The electrochemically active surface of the working electrode may be glassy carbon, gold, nickel, platinum, copper, or mercury/silver. Custom electrodes of non-listed material can be fabricated by special order.
The actual electrochemically active surface(s) in a working electrode are the centrally located “dots” in the working electrode block, as illustrated below. In some cases there may be multiple working electrodes within a working electrode block. With multiple surfaces you can further optimize the detection of multiple analytes via dual or quad electrochemical detection.
