Abstract
A method for testing enzyme based electrochemical sensors wherein an electrochemical sensor is provided. A measurement setup is provided, which is operatively coupled to the electrochemical sensor, providing an output signal Z, e.g. a measured signal current, of the electrochemical sensor; and the electrochemical sensor is suitably contacted with a test solution comprising a certain concentration of the primary analyte. The electrochemical sensor is subjected to a certain swept range of temperatures T; an output signal Z is measured for different temperature values T; a derivative Z' of the output signal Z as a function of temperature T, or inverse temperature 1/T, is determined; and a relative derivate Z′/Z at a temperature T, or inverse temperature 1/T, is determined as the ratio between derivative Z′ and output signal Z.
