This work focused on the application of symmetrical flow field-flow fractionation (Sy-FlFFF) under optimum condition to determine the hydrodynamic diameter of various types of SeNPs compared with asymmetrical flow field-flow fractionation (Asy-FlFFF) and single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) to determine the core diameter of SeNPs; and SP-ICP-MS analysis after size fractionation by Sy-FlFFF for core diameter determination of SeNPs in the mixtures. TEM and DLS are selected as reference methods because both methods are known as routine technique for nanoparticle size analysis. Use of combined techniques of Sy-FlFFF and SP-ICP-MS was demonstrated for size analysis of synthesized SeNPs size mixtures as a model of complex sample.
