Liposomes are often used as nanocarriers to encapsulate in their cores hydrophobic or highly toxic drugs, and deliver these drugs safely to target tissue. During drug nanocarrier research and development as well as production quality control, it is of great importance to monitor liposome size distributions accurately while also verifying drug encapsulation. FFF-MALS-DLS, consisting of field-flow fractionation (FFF) combined with multiangle light scattering (MALS) and dynamic light scattering (DLS), is a powerful tool for characterizing the size, concentration and structure of large nanoparticle ensembles.

DAWN®

DAWN®

The world’s most advanced light scattering instrument for absolute characterization of proteins, conjugates, macromolecules, and nanoparticles.

The DAWN and its companion Optilab dRI detector are the established benchmarks for MALS analysis, cited in thousands of peer-reviewed publications. Multi-angle light scattering detection is indispensable for use with GPC and HPLC-SEC in order to obtain reliable molecular mass distributions and information on molecular conformation, branching ratio, fragments and aggregates.

Eclipse AF4

Eclipse AF4

Versatile separations of polymers, proteins, colloids, and nanoparticles.

The Eclipse™ AF4 supports all AF4 techniques except Hollow-Fiber Flow Field-Flow Fractionation (HF5), which is covered by the Eclipse DualTec. However, the Eclipse AF4 supports the fritless AF4 channel which prevents the difficulties encountered by certain samples prone to aggregation at the relatively high concentrations typical of the AF4 focusing step. It also supports the semi-preparative channel.
