Field-Flow Fractionation and Inductively Coupled Plasma Mass Spectrometry (FFF-ICP-MS)

廠牌型號:POSTNOVA/AF 2000, Agilent/7900

Installation Date:2016.09.20

FFF-ICP-MS
  • Service:
    • AF4 used to separate macromolecules, colloids, nano- and microparticles according to their size. In AF4, the elution time is related to hydrodynamic diameter of sample. The samples are size-separated in a thin open channel with laminar flow under the influence of a perpendicular external field.
    • ICP-MS enables to detect even very low concentrations. Various elements can be traced simultaneously. AF4 coupled to ICP-MS can provide size-based elemental distributions. AF4 was also coupled to ICP-MS running in single particle mode, to generate size distributions with particle number concentrations for nanoparticles.
