Postnova Analytics reports on how Asymmetrical Flow Field-Flow Fractionation coupled to Multi Angle Light Scattering (AF4-MALS) has been successfully used to characterise a polydisperse cellulose nanocrystal for size and thickness in just 40 minutes analysis time.

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.
