Abstract
An electrochemical detection cell particularly suited for portable applications because of its small size and low cost. An enclosure is provided having two membrane surfaces. Electrodes are suspended internally between the two membranes supported by an electrochemically inert hydrophilic material containing an electrolyte solution. An improved electrode structure for use within the cell is disclosed.
