Abstract:
A method for operating a sensor to differentiate between first and second analytes in a sample, said sensor being capable of having a variable temperature profile applied thereto and said sensor generating an output profile upon sensing an analyte, the method comprising the steps of:determining a temperature profile for said sensor which will enhance the difference in the output profiles of the sensor as between the first analyte and the second analyte;determining a first analyte output profile as observed when said temperature profile is applied to said sensor;determining a second analyte output profile as observed when said temperature profile is applied to said sensor; introducing said sensor to said sample while applying said temperature profile to said sensor;obtaining a sample output profile; andevaluating said sample output profile as against said first and second analyte output profiles to thereby determine whether said first or said second analyte is present in said sample.
