Development And Application Of Scalable Two-Dimensional High Performance Liquid Chromatography For Aromatic Selective Separations Of Biologically Active Phytochemicals From Oplopanax Horridus, Gregory Jones

All Dissertations

The high demand for more efficient purification processes with increased automation and throughput pushes the development of more advanced preparative, pilot, and process scale HPLC instrumentation that is capable of achieving higher purities in a shorter amount of time than are currently achieved using one dimensional separations. A preparative scale 2D HPLC system was designed and reduced to practice in order to demonstrate the capacity for scalability of on-line comprehensive 2D HPLC separations of basic compounds from a challenging natural product extract of Oplopanax horridus. The methodology and instrumentation design herein permits direct method transfer from analytical to preparative scale …
