R. Steinert et al., IDENTIFICATION OF XYLENE ISOMERS IN HIGH-PRESSURE LIQUID-CHROMATOGRAPHY ELUATES BY RAMAN-SPECTROSCOPY, Applied spectroscopy, 51(11), 1997, pp. 1644-1647
This contribution presents a combination of high-pressure liquid chrom
atography (HPLC) with a Raman spectrometer. With this approach, we hav
e identified both isomer m-xylene and isomer p-xylene in solution at c
oncentrations down to 10(-5) mol/L. The setup was developed to analyze
compounds that cannot be separated by using standard HPLC techniques.
