Gel permeation chromatography was applied to the saturate portion of a 450 to 475/sup 0/C cut of Wilmington crude oil prepared by American Petroleum Institute Research Project 60. Selected fractions were analyzed by mass spectrometry, which demonstrated that a separation based on the number of rings was achieved. An early fraction contained 95.5 wt. percent no-, one-, and two-ring compounds; and a late fraction contained 95.9 wt. percent three-, four-, five-, and six-ring compounds. The relationship of the experimental results to those predicted from calibration curves relating carbon number to both distillation and GPC is discussed.
