Title:
METHOD FOR COMPENSATING AMPLITUDE DRIFT IN A SPECTROMETER AND SPECTROMETER PERFORMING SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2013/026466
Kind Code:
A1
Abstract:
A method of compensating for amplitude drift in a spectrometer comprising: making successive performances of a standardisation process to generate, at each performance, a mathematical transform to compensate for amplitude drift for application by an arithmetic unit to a spectrum obtained by the spectrometer in an interval between the performances; modifying the mathematical transform with a function dependent on spectral data from a zero material measured in association with the standardisation process and the single beam zero spectrum measured in an interval between performances; and applying the modified mathematical transform to a spectrum from an unknown sample.
