Poly exclusion

WebSize exclusion chromatography (SEC), also known as gel filtration, is the mildest of all the chromatography techniques. SEC separates molecules by differences in size as they pass through a resin packed in a column. Unlike techniques such as ion exchange chromatography (IEX) or affinity chromatography (AC), molecules do not bind to the ... WebThe Pauli exclusion principle requires that the bare scattering rate given by Eqn. (17) be modified by a factor 1−fm (k′) in the collision integral of the BTE, where fm (k′) is the one-particle distribution function for the state k′ in band (subband) m after scattering.
