During this period, efforts were continued to optimize the detection systems on the supercritical fluid fractionation apparatus. Experiments were conducted to improve the performance of the UV detector system. Fractionation of Wyoming Recluse Crude Oil was completed and the capillary gas chromatograms of some fractions collected during supercritical fluid fractionation of this crude oil are presented. Chemical class fractionation studies continued during this period with the evaluation of underivatized silica as a stationary phase for the separation of aliphatics from aromatics in gasoline range samples. Testing has been completed on the optical systems for steering and focusing of the laser beam and collection of the fluorescence signal. Investigation of aerosol formation in the expansion of supercritical fluids is almost complete. 10 figs., 1 tab. (PLG)
