In this study, we describe the use of different silica materials to separate vanadium compounds from Asphaltenes. We used high performance flash chromatography separation method to separate asphaltenes at different solvent strengths on sea sand. The separation conditions were optimized for flow...
The performance of highly anisotropic, nanostructured, thin-film ultrathin-layer chromatography (UTLC) media with porosity and architecture engineered using the glancing-angle deposition (GLAD) process is investigated. Anisotropic structures resembling nanoblades are fabricated on the plates,...
Development of High Efficiency and New Selectivity Liquid Chromatographic Phases for the Separation of Ionic and Hydrophilic AnalytesDownload
Separation of low molecular weight ions and hydrophilic analytes is achieved by high performance ion chromatography (IC) and hydrophilic interaction liquid chromatography (HILIC). The goal of this thesis was three-fold: to increase the efficiency of IC separations by employing small particles; to...
Analytical separations are important methods of identifying and quantifying molecular compounds present in complex sample mixtures. These approaches are popular in biochemistry, medical diagnostics, quality control, and numerous other applications. In these techniques, constituent analytes are...
