  • Method of determining physico-chemical properties of a petroleum sample from two-dimensional gas chromatography
    Patent number: 8301397
    Abstract: A method of determining physico-chemical properties of a petroleum sample from two-dimensional gas chromatography. The amounts of molecular compounds present in the sample are determined by means of two-dimensional gas chromatography. At least one physical property, such as the octane number, is then determined from these amounts. A previously calibrated relation connecting the physical property to the amounts is used to this end.
