Field-flow fractionation system

Asymmetric flow field flow fractionator (AF4, 2021) provides size-based separation of macromolecules, colloids as well as nano- and microparticles without stationary phase. Instrument is connected to DAWN 18 angle MALS detector with embedded QELS DLS detector (Wyatt), Agilent UV-Vis and fluorescence detectors and Optilab dRI detector (Wyatt). The accompanied software enables simulation of experiments and analysis of molar mass, size, conformation, conjugation and other physical parameters.
