Sg. Kazarian et al., SPECTROSCOPIC METHOD FOR IN-SITU ANALYSIS OF SUPERCRITICAL-FLUID EXTRACTION AND IMPREGNATION OF POLYMERIC MATRICES, American laboratory, 29(16), 1997, pp. 18
A novel high-pressure cell is described that permits the IR spectra of
both polymer solution and SCF solvent to be determined rapidly and se
quentially by a simple movement of the two-compartment cell within the
light beam.
