METHOD OF OPTIMIZING WAVELENGTH CALIBRATION

摘要

The present invention provides a method of calibrating the wavelength of a target instrument, based on a calibration model developed for a primary instrument. The method comprises: (a) obtaining a reference set of at least two wavelength calibration parameters for the primary instrument; (b) obtaining a target set of at least two corresponding wavelength calibration parameters for the target instrument; (c) measuring a reference spectral response of a sample with the primary instrument; (d) measuring a target spectral response of the sample with the target instrument; (e) iteratively adjusting the target set of wavelength calibration parameters; (f) for each target set of wavelength calibration parameters, determining spectral residuals corresponding to that target set; and (g) selecting an optimum set of wavelength calibration parameters based on the spectral residuals for each target set of wavelength calibration parameters.
