Ion-exclusion chromatography: Analysis and isolation of nucleic acid components, and influence of separation parameters

Ion exclusion, a manifestation of the Donnan effect, separates ionized from nonionized substances by excluding the former and utilizes the same ion-exchange materials as does ion exchange but at desorbing, as opposed to absorbing conditi...
