Postnova Analytics reports on how Thermal Field Flow Fractionation has been successfully used to elucidate the core microstructure, morphology and chain arrangement of self-assembling block copolymers. This pioneering study was undertaken by the renowned research group under Professor H Pasch at the Department of Chemistry and Polymer Science, University of Stellenbosch (South Africa).
Postnova Analytics has published a new application note that describes a new approach for analysis of titanium dioxide nanoparticles in commercial sunscreens. The technique, which combines Inverse Supercritical Fluid Extraction (I-SFE) and Miniaturized Asymmetrical Flow Field-Flow Fractionation hyphenated with UV-Vis and Multi Angle Light Scattering (mAF4-UV-MALS) represents a promising tool for the verification of the nano-labelling of such products.
Postnova Analytics report on how researchers from the Institute for Health and Consumer Protection at the European Commission Joint Research Centre (Ispra, Italy) and the University of Ferrara have used AF2000 Asymmetric Flow Field-Flow Fractionation (AF4) system and Model S101 Sedimentation Flow-Field Fractionation (SdFFF) systems in some ground-breaking research.
Enjoy our new publication that shows how Asymmetrical Flow Field-Flow Fractionation coupled with ICP-MS can help understanding the fate and transformation of AgNP at trace levels in soils over time.
