High Resolution: AF4 provides high-resolution separation of particles ranging from a few nanometers to several micrometers. Versatility: It can handle a wide range of sample types, including biological macromolecules, polymers, and inorganic nanoparticles. Non-destructive: The absence of a stationary phase minimizes the risk of sample alteration or degradation. Scalability: AF4 can be scaled for both analytical and preparative purposes, making it suitable for research and industrial applications.
