Supercritical Fluid Chromatography and Extraction

“…Bartle et al used simulated-distillation SFC in their investigation of progress in the co-refining of coal and petroleum (211). Campbell et al also used SFC (with MS detection), along with a variety of other techniques, in the characterization of nondistillable coal liquefaction process streams (212).…”
