Flow field-flow fractionation
WebThe book "Field-flow Fractionation: Analysis of Macromolecules and Particles by Josef Janča has been maybe the first real book completely focusing on FFF. If compared with other FFF books, which have been published later, especially for example with the most famous "Field-Flow Fractionation Handbook", the book of Janca is really unique as ... WebFlow field-flow fractionation (F4) is the gentlest flow-assisted separation technique for analysis of macromolecules. The use of an empty channel as separation device and of a second mobile phase flow as perpendicular field enable F4 to separate analytes under native conditions without any modification of their original structure. Because of ...
