Abstract
A method for standardizing a spectrometer generating an optical spectrum from a sample, comprising generating at least one optical spectrum from at least one standardization sample each having a chemical composition resulting in the optical spectrum showing a characteristic pattern in a predetermined frequency range, comparing information relating to the pattern(s) to corresponding information relating to at least one reference pattern previously defined as the desired standard response from the at least one standardization sample, determining, based on the comparison, standardizing parameters describing the transition of the pattern(s) of the generated spectrum or spectra to the reference pattern(s) and storing said standardizing parameters in the spectrometer or a computer connected thereto, so that the spectrometer, when presented to an unknown sample, will, using the standardization parameters, generate an optical spectrum substantially identical to that which would be generated in a corresponding spectrometer standardized with a sample of the same chemical composition using the same previously defined reference pattern(s). The present method relates to standardization of the i…
