ABSTRACT:
This invention relates to a method for rapidly determining weight and volume percent true boiling point curves for crude oils and fractions thereof. The method involves at least a partial separation of the crude oil or fraction into constituent chemical components, obtaining mass spectra of the chemical components, correlating retention time windows with boiling points for standard hydrocarbon mixtures, and converting the total ion current obtained from the mass spectra for selected components to weight and volume percent true boiling points by comparison with data obtained from a standard crude oil or fraction thereof.
