Abstract:
The objective of this analytical technique is to differentiate saturate, olefins and aromatics (mono-, di-, and tri-) in a single sequence using supercritical fluid chromatography and simultaneous UV detection to identify component regions by also confirming carbon numbers. The analysis focuses on pyrolysis process liquids that are capable of being dissolved and filtered using suitable solvents and filters. Aromatics, Saturates and Olefins regions are cross referenced with UV-detector results at different absorption wavelengths to determine the approximate carbon number of the saturates and olefins. The standalone UV-detector also allows for further distinction of the mono-, di-, and tri- aromatic regions by simultaneously overlaying chromatograms and spectra.
