Abstract
A method to simulate distillation of a petroleum stream by gas chromatography can include separating the petroleum stream with a gas chromatograph as a function of boiling point; passing the separated petroleum stream through a vacuum ultraviolet detector to yield data comprising a vacuum ultraviolet signal as a function of boiling point; integrating the vacuum ultraviolet signal as a function of boiling point over two or more wavelength ranges to derive relative concentrations of two or more components of the separated petroleum stream that correspond to the two or more wavelength ranges.
