Fabrication of porous polymer monoliths covalently attached to the walls of channels in plastic microdevices
UV‐initiated grafting of plastic tubes and microfluidic chips with ethylene diacrylate followed by the preparation of porous polymer monoliths has been studied to prevent the formation of voids at the monolith‐channel interface. Expand
Recent advances in polymer monoliths for ion-exchange chromatography
In this review different strategies for the synthesis of polymeric monoliths with ion-exchange functionality are discussed, as also are different post-polymerization alterations to the monolith surface such as grafting. Expand
Towards high capacity latex-coated porous polymer monoliths as ion-exchange stationary phases.
The preparation of high capacity agglomerated monolithic ion-exchangers for capillary ion chromatography is described and the reaction with sodium sulfite resulted in the most significant increase in the capacity and the best separation performance. Expand
Tryptophan metabolism, its relation to inflammation and stress markers and association with psychological and cognitive functioning: Tasmanian Chronic Kidney Disease pilot study
The results of this preliminary study suggest the involvement of inflammation in tryptophan breakdown via the kynurenine pathway, yet without sparing tryPTophan metabolism through the 5-HT (serotonin) pathway in CKD patients. Expand
Photografting and the Control of Surface Chemistry in Three-Dimensional Porous Polymer Monoliths
The photografting of porous three-dimensional materials has been achieved using a benzophenone-initiated surface photopolymerization within the pores of a macroporous polymer monolith contained in aExpand
Identification of inorganic improvised explosive devices by analysis of postblast residues using portable capillary electrophoresis instrumentation and indirect photometric detection with a
Profiling the ionic composition of the inorganic IEDs allowed identification of the chemicals used in their construction and use of the portable instrumentation in the field was demonstrated. Expand
Controlling the surface chemistry and chromatographic properties of methacrylate-ester-based monolithic capillary columns via photografting.
Preparation of monolithic capillary columns for separations in the CEC mode using UV-initiated polymerization of the plain monolith followed by functionalization of its pore surface by photograftingExpand
Identification of homemade inorganic explosives by ion chromatographic analysis of post-blast residues.
The efficacy of the developed methods was demonstrated by analysis of residue samples taken from witness plates and soils collected following the controlled detonation of a series of different inorganic homemade explosives. Expand
Simple and robust determination of monosaccharides in plant fibers in complex mixtures by capillary electrophoresis and high performance liquid chromatography.
Free solution capillary electrophoresis (CE) can be used without derivatization at pH 12.6 and was found to provide a higher resolution of galactose and xylose than common LC with no sample pre-treatment required, other than dilution, within 26min. Expand
Charge heterogeneity profiling of monoclonal antibodies using low ionic strength ion-exchange chromatography and well-controlled pH gradients on monolithic columns.
In this work, the suitability of employing shallow pH gradients generated using single component buffer systems as eluents through cation-exchange (CEX) monolithic columns is demonstrated for theExpand
