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.
