Advantages of field-flow fractionation
This brochure from Postnova, gives information on the advantages of field-flow fractionation.

Characterization of metal-containing nanoparticles in tattoo ink using AF4 coupled with MALS and ICP-MS
This study demonstrates the excellent suitability of AF4-MALS-ICP-MS for the comprehensive characterization of tattoo inks. Besides the particle size distributions obtained from the MALS data, ICP-MS additionally allows statements on the elemental distributions of various metals as a function of the respective particle sizes, providing valuable insight into the composition of the inks.

Characterization of tau protein aggregates with AF4 and UV-MALS-DLS
In this study, tau protein samples were analyzed by asymmetrical flow field-flow fractionation (AF4) coupled with UV/Vis, multi angle light scattering (MALS) and dynamic light scattering (DLS) detection to characterize 1) the protein monomer, 2) the protein fibril aggregate, and 3) the protein fibril aggregate after bath sonication.

Characterization of ribosomal RNA using AF4 and MALS
In this application, two escherichia coli ribosome samples obtained from different growth procedures were analyzed by AF4-UV-MALS and compared with a control sample. The change in relative amount of the active ribosome compared to those of subunits may provide essential information to design optimal growth procedures.

Quantification of liposome-encapsulated drug using centrifugal field-flow fractionation
In this application, centrifugal field-flow fractionation coupled with UV-Vis detection was able to separate and quantify the amount of free drug in a liposome-drug product. The separation was verified using optical microscopy.
