SENSOR CALIBRATION METHOD AND APPARATUS

摘要

Disclosed is a method of calibrating an apparatus comprising at least one sensor for detecting one or more analytes of interest in a sample, the method comprising measuring a first set of responses of the at least one sensor to at least one first calibration solution having a known composition of the one or more analytes of interest; measuring 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 the composition of the second calibration solution from the difference between the first set of responses and the second response; and periodically calibrating the at least one sensor with the second calibration solution using said determined composition. An apparatus and computer program product for executing this method are also disclosed.
