Colloidal aspects and packing behaviour of charged microparticulates in high efficiency ion chromatography

► Goal is to understand the slurry packing process of high efficiency polymeric phases. ► Development of tests to predict column efficiency using sulfonated resin as a model. ► Investigation of colloidal and non-Newtonian behaviour during packing. ► Counter-ion charge and ionic strength of the slurry can affect column efficiency. ► Control of a shear thickening and temperature manipulation of a slurry is helpful.
