Chromatographic Media for Liquid Phase Separations
Separation science has advanced tremendously because of the contributions of many researchers, creating fundamental and cumulative knowledge on which we continue to build. Many aspects have evolved in the past 20-25 years. One of such aspects has been the development and study of new separation media for liquid chromatography (LC), which relies on material chemistry to provide stable and affordable chromatographic phases. Chromatographic media today provide high separation efficiency using small particulates, phases with varied selectivities, and materials improved hydrolytic stability. The later, for example, provides the opportunity to further tune selectivity by means of pH and/or temperature, which in turn offers a wider range of capabilities to design a separation method with a given stationary phase. Our research group has investigated different areas in separation science with strong interest in chromatographic media. These investigations have led to the synthesis of stable hybrid silicas in the monolithic and particulate formats, studies of submicron hybrid particles for separations under ultrahigh pressure liquid chromatographic and capillary elelctrochromatographic modes, as well as exploring non-silica materials. The work has also included preparation of nanodiamond layers on silica particles, studies of carbon nanoparticles, and the use of non-traditional chemistries on the surface of superficially porous silica particulates to study their chromatographic properties. In this presentation, we will provide an overview of our efforts through the years that have contributed to the advancement of separation science, and highlight our recent silica modification approaches to produce chromatographic phases for liquid phase separations. The presentation is also a tribute to the number of researchers from different backgrounds who created an enriched environment in our laboratories to pursue research in the chemical separation science.
