Abstract
Methods and apparatus () for Raman spectral analysis of a sample (), such as a pharmaceutical dosage form, are disclosed. Delivery optics () are used to deliver probe light to a delivery region () on the sample, and collection optics () are used to collect, from a collection region () on the sample spaced from the delivery region, the probe light following scattering through the sample. Each of a plurality of target Raman spectral features are measured in the collected light, and a spectral distortion of the collected light arising during scattering through the sample is determined. A property of the sample is then quantified using the target Raman spectral features in combination with the determined spectral distortion, such that the quantified property is compensated for the spectral distortion.
