Abstract: Methods and systems are described for performing spectroscopic measurement of at least one analyte of interest in an inhomogeneous sample using a spectroscopic system. This generally involves generating and aiming an illumination beam which forms a focal region having focal region size S upon a surface or within a volume of the sample where there is relative motion between the sample and the focal region at a relative speed V; selecting a desired ratio between an exposure time E for a detector of the spectroscopic system and a transit time T for a particle of the at least one analyte of interest to traverse the focal region; acquiring one or more spectral data sets corresponding to spectra for a region of the sample within the focal region; and analyzing the one or more spectral data sets to generate one or more corresponding analytical results.

Abstract: Various embodiments are provided herein for a Raman analyzer system and associated method of analyzing a chemical process including a supercritical fluid extraction process or a solvent extraction process using a Raman analyzer system where the method involves generating light stimuli and providing the light stimuli to a sample of the chemical process; collecting scattered light from the sample; filtering the scattered light using one or more selected optical filters for selectively attenuating one or more wavelength sections for Raman analysis; detecting the filtered light; and generating one or more filtered Raman spectra of the detected light.
