摘要：
High-gradient magnetic field (HGMF) split-flow thin channel (SPLITT) fractionation (HGMF-SPLITT) is a newly developed magnetic fractionation technique for separating submicron and/or nanoscale paramagnetic particulate species in a continuously flowing separator. Incorporation of high-gradient magnetic fields, into the split-flow-fractionation separator geometry, increases the magnetic force experienced by a paramagnetic submicron particle relative to current magnetic field-flow-fractionation devices. The application of HGMF-SPLITT fractionation, for selective separation of paramagnetic submicron particulates, was experimentally investigated.
