ACCESSORY FOR ATTENUATED TOTAL INTERNAL REFLECTANCE (ATR) SPECTROSCOPY

摘要

A method of carrying out automated attenuated total internal reflectance spectral analysis comprises acquiring a spatial image of a sample and processing the image, wherein the processing steps comprise differentiating the acquired image in the spectral domain, restricting the spectral range of the image, subtracting an average absorbance from the restricted image data, and applying a principal components analysis to extract the most significant spectral features, and by the further step of displaying, to the user, a spatial image showing the most significant spectral features of the sample.
