For the period of June through August effort was concentrated on instrumental development and column technology. The fluorescence detection supercritical-fluid chromatography (SFC) system was equipped with fiber optics. Computer-controlled, rapid-scanning was developed and tested for the fluorescence SFC. A third SFC system was designed and constructed with flame ionization detectors. This system was designed for the evaluation of carbon dioxide and other similar potential mobile phases. Asphaltene fractions were obtained and characterized by uv spectroscopy as a preliminary to chromatographic analysis. A new stationary phase for SFC was synthesized and evaluated. Considerable effort was expended to resolve the technical difficulties of coating narrow-bore capillary columns. 9 figures, 1 table.
