Interests: capillary liquid chromatography; monolithic column design and preparation; organo-silica monolithic structures; inorganic monolithic structures; surface modifications of porous monoliths
In recent years, many exciting discoveries have taken place in the area of separation science. At the forefront is the development and improvement of monolithic column technology, mainly for applications in liquid chromatography, capillary electrochromatography, and occasionally, gas chromatography. Interest in monoliths as stationary phases has been stimulated by the promise of achieving fast and efficient separations, so as to permit rapid high-throughput analysis. Enthusiasm for making monoliths in one's own laboratory has also contributed to interest. Consequently, this Special Issue is dedicated to showcasing the latest research findings related to the role of monolithic columns in separation science, starting from column design and preparation, to the characterization of column properties and performance, to the wide range of applications for commercial as well as custom-made columns.

Abstract: This work presents the first instance of reversed phase liquid chromatographic (RP-HPLC) separation of small molecules using graphene oxide nanoparticle modified (GONP) Polystyrene-divinylbenzene polymeric high internal phase emulsion (PS-co-DVB polyHIPE) materials housed within 200 µm i.d. fused silica capillary. The GONP modified materials were produced as a potential strategy to increase both the surface area limitations and the reproducibility issues observed in monolithic stationary phase materials. GONP PS-co-DVB polyHIPEs were found to have a surface area up to 40% lower than unmodified polyHIPE stationary phases. However, despite having a surface area significantly lower than the unmodified material, the GONP modified polyHIPEs demonstrated superior analyte adsorption properties. Reducing the GONP material did not have any significant impact on elution order or retention factor of the analytes, which was most likely due to low GONP loading attributed to the large GONPs utilised. The lower surface area GONP modified polyHIPEs provided similar separation efficiency and increased repeatability from injection to injection resulting in %RSDs of less than 0.6%, indicating the potential offered by GO modified polyHIPES in flow through applications such as adsorption or separation processes.
