Sutthinee Mekprayoon and Atitaya Siripinyanond* The ability of using flow field-flow fractionation (Fl-FFF) coupled off-line with electrothermal atomic absorption spectrometry (ETAAS) for size characterization of AuNPs was investigated. The carrier liquid and membrane affected on particle/membrane or particle/particle interactions in Fl-FFF separation channel. Using DI water with 10 kDa RC membrane provided the best separation of … Continue reading Performance Evaluation of Flow Field-Flow Fractionation and Electrothermal Atomic Absorption Spectrometry for Size Characterization of Gold Nanoparticles
