This report gives information on the development of a procedure to fractionate bitumen using an Iatroscan liquid chromatography system, and also presents test results on a range of Australian bitumens. An introduction discusses the topic of bitumen fractionation and emphasises that all bitumen fractionation procedures are arbitrary - there is no widely accepted single way of categorising bitumen constituents.
