Chromatography Purification High Impact Factor Journals Chromatography is an analytical technique which is used for purification of components based on the process of separation of components based on the interaction of the component with both stationary and mobile phase. The scope includes chromatography and related techniques (e.g. field-flow fractionation), electromigration techniques, hyphenated and other multi-dimensional techniques, sample preparation , and detection methods such as mass spectrometry.
