Abstract
A method and test element for electrochemically detecting at least one analyte in a sample are provided, wherein the method comprises: a) providing at least one test element comprising at least one first electrode contacting a test chemistry and at least one second electrode, wherein a surface of the second electrode consists of silver metal; b) contacting both the first and second electrodes with the sample comprising chloride ions; c) applying a first voltage between the first electrode as a cathode and the second electrode as an anode with a voltage sufficient for forming a layer of silver chloride at the surface of the second electrode; d) applying a second voltage between the first electrode as the anode and the second electrode as the cathode; and e) determining an electrical signal between the first and the second electrodes, whereby the analyte in the sample comprising the chloride ions is detected.
