Abstract
Compensating for amplitude drift in a spectrometer may include making successive performances of a standardization 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. The compensating may include modifying the mathematical transform with a function dependent on spectral data from a zero material measured in association with the standardization process and the single beam zero spectrum measured in an interval between performances. The compensating may include applying the modified mathematical transform to a spectrum from an unknown sample.
