Abstract

Alternatives to conventional gas chromatographic simulated distillation methods for high boiling materials are reviewed. Operational parameters for the use of supercritical fluid chromatography for simulated distillation are explored and examples for the analysis of both petroleum and coal‐derived samples are compared to conventional gas chromatographic methods and thermogravimetric analysis. Extension of the boiling range determined by simulated distillation to over 800°C is demonstrated. An n‐ octylpolysiloxane stationary phase minimized the aliphatic versus aromatic boiling point discrepancy common to other chromatographic methods.
