Abstract:
A method of standardizing spectral information for a sample in a spectrometric instrument that effects an intrinsic distortion into spectral data, the instrument including an optical train with spectral means for effecting a spectral beam responsively to a sample such that the spectral beam is characteristic of the sample, detector means for detecting the spectral beam to effect signal data representative thereof, computing means receptive of the signal data for computing corresponding spectral information representative of the sample, and display means for displaying the spectral information, the optical train including an optical component selectively having a standardizing condition or an operational condition, such condition having the intrinsic distortion associated therewith, and the sample being selectable from a sample set including a test sample and one or more standard samples formed of a substance having true spectral data, wherein the method comprises steps of:specifying an idealized function of spectral line shape for a hypothetically sharp spectral line, obtaining standard spectral data for a standard sample with the standardizing condition, establishing a standard function that relates the standard spectral data to the true spectral data, and storing the idealized function, the standard spectral data and the standard function in a selected format for future application to test spectral data to effect standardized spectral data.
