“…Until recently, supercritical fluid chromatography suffered from long separation times as well as complicated, expensive equipment; however, separation of up to 42 styrene oligomers has been reported (4,5). Several workers have investigated reversed-phase (6)(7)(8)(9)(10) and adsorption chromatography (9)(10)(11)(12) on microparticulate media as time-saving alternatives. Rapid, efficient separations of several oligomers have been obtained from both modes of high-performance liquid chromatography.…”
