TEST ELEMENT ANALYSIS SYSTEM WITH CONTACT SURFACES COATED WITH HARD MATERIAL

摘要

The invention relates to a test element analysis system (1) for analytical investigation of a sample, in particular a body fluid, comprising at least one test element (3) with one or more measuring zones (7), contact surfaces (11) located on the test element (3), in particular, electrodes or conductors, whereby the sample under investigation is applied to the measuring zone (7) to perform an analysis by determination of a parameter characteristic for the analysis, and an analytical device (2) with a test element retainer (5) for positioning the test element (3) in a measuring position and a measuring device for measuring the characteristic change, whereby the test element retainer (5) comprises contact elements (14) with contact surfaces (12) which permit an electrical contact between the contact surfaces (11) of the test element (3) and the contact surfaces (12) of the test element retainer (5), characterised in that one of said contact surfaces is provided with an electrically-conducting hard material surface (20). The invention relates particularly to the coating of a contact surface (12) of the contact connection on a test element analysis device with an electrically-conducting hard material.
