Asymmetric-Flow Field-Flow Fractionation (AF4) is an advanced technique for achieving analytical and semi-preparative separations, applicable to a wide range of analytes including proteins, polymers, nanoparticles, colloids, and complex fluids.
Even the most complex macromolecular solutions and colloidal particle suspensions can be analyzed utilizing multiple online detection methods after separation by AF4, from UV and light scattering to ICP-MS. Wyatt Technology offers both complete solutions for FFF and upgrades to existing HPLC or SEC systems for FFF capabilities. |
