ABSTRACT:
A method is provided for transferring spectral information, comprising spectral images, from a source spectrometer to a target spectrometer in order that chemometric models can be transferred among spectrometers. The method comprises passing substantially monochromatic atomic lines into a source and target spectrometer and displaying a spectrum of light intensity for each spectrometer, developing a correlation between the spectra of light intensity such that the location and shape of the target spectrometer correlated spectrum can be expressed as a function of the source spectrometer, processing a known sample into the source spectrometer and displaying spectral images, developing a transformation for the spectral images from the source spectrometer such that the correlated and transformed spectral images are transformed to appear substantially similar to the spectral images of the sample measured with the target spectrometer, and generating a chemometric model to relate the correlated and transformed spectral images from the target spectrometer to the physical properties of the sample corresponding to the spectral images.
