• Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization
  

  High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more
