✦ Synopsis

A sample of whole Athabasca bitumen has been fractionated by preparative g.p.c. The weights of the fractions have been determined and their molecularweights measured by several methods. In contrast to previously published data, consistent results were obtained using different solvents (THF, benzene/water) and using different techniques (v.P.o., f.p.d. and g.c.-m.s.). This has resulted in an accurate definition of the molecular weight distribution of Athabasca bitumen.
