Each of the following statements describes a type of column chromatography. Sort the statements to the type of chromatography they describe. If a statement can describe all of the types, place that statement in the "All" category. (Note that size-exclusion chromatography may also be called gel-filtration or molecular exclusion chromatography.)Categories: Size-exclusion Chromatography, Affinity Chromatography, Ion-exchange Chromatogrpahy, and AllStatements:Separate molecules by size. Separate molecules by charge. The stationary phase has a covalently bound group to which a protein in the mobile phase can bind. Uses a mobile phase and a stationary phase to separate proteins. The stationary phase contains cross-linked polymers with different pore sizes. Can separate molecules based on protein-lignand binding. The stationary phase may contain negatively or positively charged groups.
