Abstract
An analyzer for analyzing a composition of a sample, and methods of operating an analyzer. The analyzer may include an optical illuminator and a Raman spectrometer to produce Raman spectral data representative of Raman radiation emitted from the sample in response to the illuminating light. Features to reduce background fluorescence are optionally provided. An x-ray illuminator may be provided to illuminate the sample with x-rays, and also an x-ray spectrometer may be present to produce x-ray spectral data representative of fluorescence radiation emitted from the sample in response to the illuminating x-rays. A processor receives the Raman spectral data and any x-ray spectral data and provides an analysis of a compound in the sample.
