1. A method of calibrating an apparatus (400) comprising at least one sensor (412, 414, 416, 418) for detecting one or more analytes of interest in a sample, the method comprising:

  • measuring (110, 120) a first set of responses of the at least one sensor to at least one calibration solution having a known composition of the one or more analytes of interest;

    measuring (130) a second response of the at least one sensor to a second calibration solution having an approximately known composition of the one or more analytes of interest;

    determining (140) the composition of the second calibration solution from the difference between the first set of responses and the second response; and

    periodically calibrating (150) the at least one sensor with the second calibration solution using said determined composition.
