Hyaluronic acid application using AF4 - SLS/RI
AF4 allows for a very fast, gentle and interaction free separation without the effect of a stationary phase. It makes possible the separation of complex matrices without sample preparation or filtering prior to injection.

Characterization of virus and aggregates using AF4-MALS
This application note shows how AF4 can be used for the fast (ca. 20 min) and high resolution characterization of viruses and their aggregates. This makes the technology an important standard tool in modern pharmaceutical/biotechnology sciences.

Characterization of virus and proteins using AF4-SLS/DLS
AF4 allows for a fast, gentle and nearly interaction free separation without a stationary phase. It makes possible high resolution separations of proteins, viruses and aggregates simultaneously over a broad size range, and separations of complex mixtures without intensive sample preparation, filtering or centrifugation.

Characterisation of monoclonal antibody aggregates using AF4-UV/Vis
Although asymmetric flow FFF offers similar information as SEC, the lack of packing material leads to significant advantages for AF4, specifically low shear conditions so that aggregates are not degraded

Protein aggregation study with ferritin using AF4-UV/Vis
In this application note, results from the characterization of ferritin are presented, as an example for a protein which is forming aggregates.

Protein aggregation study BSA using AF4-UV/Vis
This application note describes results from the FFF characterization of BSA, bovine serum albumin, as an example for a protein which is forming aggregates.

Kinetic study of aggregation of milk protein and/or surfactant-stabilized oil-in-water emulsions by sedimentation field-flow fractionation
This study employed sedimentation field-flow fractionation (SdFFF) to monitor changes in particle size distribution of freshly prepared emulsions with varying weight contributions of sodium caseinate (SC) and whey protein concentrate (WPC).

Postnova SF2000 GS (Gravitational SPLITT) series
SPLITT fractionation utilizes the well-controlled hydrodynamics found in thin cells and the simplicity and flexibility of an externally applied field. The high stability of flow leads to high resolution separations and reproducible results.

Postnova model 3700 DLS Zetasizer Nano
The Postnova PN3700 DLS Zetasizer Nano brings you the practiality of a maintenance-free system with the versatilty to offer precision measurement for your laboratory's particle characterisation needs in a single compact unit. It allows determininig the particle size, the zeta potential and the molecular weight.

Postnova model 3700 DLS series
High sensitivity online dynamic light scattering detector, special customized for use connected to field-flow fractionation (AF2000, CF2000 and TF2000).
