This is a timely collection of important biomedical applications for a set of separation/characterization techniques that are rapidly gaining popularity due to their wide dynamic range, high resolution, and ability to function in most commonly used solvent systems. Importantly, the field-flow fractionation (FFF) technique has recently emerged as a prominent complement to size exclusion chromatography for protein pharmaceuticals. Fractionation with FFF is gentle and preserves protein structural integrity better than existing alternatives. In the present text, different chapters are written...
