Continuous size fractionation of magnetic nanoparticles by using simulated moving bed chromatography

Carsten-Rene Arlt, Dominik Brekel, Stefan Neumann, David Rafaja, Matthias Franzreb

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 5,   Pages 1346-1355 doi: 10.1007/s11705-021-2040-3

Abstract: Using magnetic chromatography, we show a promising method for fractionation of magnetic nanoparticleswith respect to their size and/or magnetic properties.concept was transferred into a continuous process in this work using a so-called simulated moving bed chromatographyDue to the easy scalability of continuous chromatography, the process is a promising approach for theefficient fractionation of industrially relevant amounts of magnetic nanoparticles.
