Book Description
Field flow fractionation (FFF) is an emerging separation technique, which has been proven successful in the analysis of pharmaceuticals, biotechnology products, polymers, soils, and foods, among others. In this book, Martin Schimpf joins forces with Karin Caldwell and J. Calvin Giddings, two of the primary developers of this technique, to bring you the first comprehensive, one-stop reference on the technique.

Book Description
Field-flow fractionation has become a very effective method for the separation and analytical characterization of substances of macromolecular and particulate character-making this method probably the most important discovery in the analytical separation field since World War II. The first, complete, up-to-date reference on this notable separation method, Field-Flow Fractionation includes comprehensive explanations of general and theoretical principles . . . presents detailed descriptions of experimental techniques and instrumentation ... and discusses advantages over competitive processes. In addition, this resource demonstrates various applications for characterizing synthetic polymers ... analyzing biopolymers and particles in environmental samples ... and determining sizes of biological cells, viruses, and subcellular particles. Substantiating main conclusions of theories, experiments, and applications with graphs and drawings, and including numerous tables and photographs, this one-source reference is invaluable reading for analytical, industrial, physical, and polymer chemists; chrom atographers; biochemists; biotechnologists; biophysicists; and all others interested in the study and characterization of macromolecules or particles of various origins.

Book Description
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 by experts in their respective field of application, who offer comparisons between the FFF techniques and other methods for characterizing their special focus material. Practical guide-lines for successful implementation, such as choice of operating conditions, are offered in conjunction with each application. In addition to new instrumentation and approaches that address important current topics, readers are provided with an overall sense of prior (but timeless) major developments that may be overlooked in literature searches.

Book Description
Nanoparticles are the building blocks for nanotechnology; they are better built, long lasting, cleaner, safer, and smarter products for use across industries, including communications, medicine, transportation, agriculture and other industries. Controlled size, shape, composition, crystallinity, and structure-dependent properties govern the unique properties of nanotechnology. Bio-Nanoparticles: Biosynthesis and Sustainable Biotechnological Implications explores both the basics of and advancements in nanoparticle biosynthesis. The text introduces the reader to a variety of microorganisms able to synthesize nanoparticles, provides an overview of the methodologies applied to biosynthesize nanoparticles for medical and commercial use, and gives an overview of regulations governing their use. Authored by leaders in the field, Bio-Nanoparticles: Biosynthesis and Sustainable Biotechnological Implications bridges the gap between biology and technology, and is an invaluable resource for students and researchers alike.

Book Description
The two companion volumes of Advances in Polymer Science - Volumes 150 and 151 - deal with recent progress in the characterization of polymers, mostly in solution but also at surfaces. The contributions comprise multidimensional chromatography for elucidation, the composition and the chain length distribution of copolymers, capillary electrophoresis of synthetic water-soluble polymers including polyelectrolytes, field flow fractionation techniques for quick and reliable separation and characterization of broad polymer samples and a novel application of thermal grating experiments for probing Brownian and thermal diffusion. Finally the rapid development of atomic forces techniques is reviewed with particular emphasis on the visualization of macromolecules and the patterning of surfaces.

Book Description
"Size separation of spherical and rod-like particles in Flow Field-flow Fractionation was investigated theoretically. The effect of cross flow migration and rod orientation was also investigated as a new mode of study. It has been shown that the rod local orientation makes different diffusivity values in comparison with spherical particles and helps particle separation. Additionally, a new mechanism of lift-hypelayer mode was used for rod-like particles which can be compared with steric mode of spherical particles. This mechanism is said to be due to hydrodynamic interaction of rod-like particle with wall and with other rods. As a measure of axial and cross flow velocity, Peclet number was defined in each case with respect to spherical particle or rod-like particle. Based on different Peclet numbers, operations were divided into four different regions each with a dominant mode. Additionally, retention ratio of each particle category was calculated using concentration profile and velocity profile. Summing up all the effects, the conclusion was drawn that according to what size of particle to separate, one should choose proper axial and cross-flow velocity together with proper mode of operation. Finally, based on theoretical studies, it was concluded that shape separation of rod-like particles is feasible for particles in micro size. However, for smaller particles experimental investigation may be needed."--Abstract, page iv.
