  • Electrochemical sensors for testing water
    Patent number: 10241072
    Abstract: An electrochemical sensor for the detection and analysis of an analyte in a solution is disclosed. The electrochemical sensor has an electrically non-conductive support; a plurality of electrodes on the support, each electrode formed from an electrode material and having a first surface and an opposite second surface, said first surface facing towards the support and the second surface facing away from the support. The plurality of electrodes includes a reference electrode, a counter electrode, and a working electrode. The working electrode has a reagent composition containing a reagent for detecting an analyte applied directly to the second surface of the working electrode or dispersed throughout the electrode material of the working electrode.
    Type: Grant
    Filed: September 23, 2013
    Date of Patent: March 26, 2019
    Assignee: ARCH CHEMICALS, INC.
