Abstract:
An analytical system for high-throughput analysis of polycarbonate synthesis, comprising:a plurality of analytical samples each comprising at least one analyte, wherein said analyte comprises at least one reagent, intermediate, or product of a polycarbonate synthesis reaction; an analytical matrix comprising a plurality of spatially differentiated analytical sites, each site comprising at least one sorbent material, wherein said sorbent is selected from the group consisting of activated carbon, silica, alumina, diatomaceous earth, zeolite molecular sieves, carbon molecular sieves, graphitized carbon-based adsorbents, metallic particles, semiconductor particles, dielectric particles, polymeric sorbents, and mixtures thereof; a sample loader capable of handling a plurality of samples for delivering a known amount of each analytical sample onto at least one analytical site; a light source for irradiating the at least one analytical site on the matrix with a first wavelength range; a detector for detecting a Raman spectroscopic characteristic of the analyte directly from the at least one analytical site on the matrix with a second wavelength range, wherein said Raman spectroscopic characteristic is specific to the analyte and not the sorbent; and a computer for determining a concentration of the analyte at the at least one analytical site based on the spectroscopic characteristic.
