Abstract:
1. A method of calibrating an optical analysis system being adapted to determine an amplitude of a principal component of an optical signal by making use of a multivariate optical element and a detector, the method of calibrating comprising the acts of: determining the principal component of the optical signal being obtained from a first reference sample; deriving at least a first parameter of the first reference sample by making use of the principal component; performing a comparison between the at least first parameter with at least a first reference parameter of the first reference sample; determining at least a first calibration value for the at least first parameter by making use of the comparison, the at least first calibration value being applicable for calibrating the optical analysis system; and deriving an at least second parameter of the optical analysis system from an output signal of the detector in absence of the first reference sample and/or in absence of optical radiation, the at least second parameter being representative of system inherent noise and being applicable for calibrating the optical analysis system.
