Abstract

Common industrial analytical procedures determine the overall physical or chemical characteristics of a petroleum product, which are necessary to market the product, but these methods provide little or no information concerning specific chemical components. This article focuses on standard methods which can be used to determine the composition of individual components or classes of components within various petroleum matrices. Gas chromatography (GC) coupled with low-resolution mass spectrometry (MS) is the most useful method for quickly identifying and precisely measuring specific components or classes of components in a petroleum matrix. Direct insertion probe mass spectrometry/mass spectrometry (DIP/MS/MS) can be used for less volatile and thermally labile petroleum components.
