Patent ID: 7405821

Claim:
A method of standardization for a spectroscopic device comprising the steps of: providing a detector; simultaneously stimulating a sample and a comparison material; producing a first signal indicative of a test spectral line or spectrum of at least one component contained in the sample using the detector; producing a second signal indicative of a comparison spectral line or spectrum of the known comparison material using the detector; comparing the second signal indicative of the comparison spectral line or spectrum produced using the detector with an ideal comparison spectral line or spectrum to calculate a transfer function derived from the comparison spectral line or spectrum and the ideal comparison spectral line or spectrum, the transfer function derived independently of the sample spectral line or spectrum; applying the transfer function to the test spectral line or spectrum to calculate a corrected test spectral line or spectrum; and wherein the ideal comparison spectral line or spectrum is generated based on prescribed values of parameters selected from the group consisting of: temperature, pressure, mechanical wear of the spectroscopic device, the setting of the spectroscopic device, and points of measurement.
