This paper presents a theoretical treatment of nanoparticle retention in quadrupole magnetic field-flow fractionation (QMgFFF) using a helical separation channel. It defines the retention ratio as the ratio of transit times for non-retained versus retained material. Equations are derived for angular and longitudinal…
