This review highlights applications for which AF4 is particularly well suited, and explains when not to use the technique.

Characterization of macromolecules and colloids is an area of considerable interest. Asymmetrical flow field-flow fractionation (AF4) has become a well-established method, but many potential users possess limited knowledge of its capabilities, or how it can provide additional information or serve as validation to the traditional analytical techniques. This review article highlights several practical applications where AF4 should be given special consideration, and discusses benefits and drawbacks of the different methods.
