  • Unit for the determination of absolute molecular weights and molecular structures of complex polymer systems

    The set of liquid chromatography available to POLYMAT presents a combination of detectors and separation systems that make it unique. This equipment allows to determine not only the absolute molecular weight but also the radius of gyration and the hydrodynamic radius at each time/volume of elution. In addition, it allows the determination of molecular weights in a very wide range: from low molecular weight polymers to polymers of extremely high molecular weights (up to 10^9 Da). It also allows to characterize not only linear polymers but also cross-linked polymers and with complex architecture.
