Each of the given statements describes a type of column chromatography. Match 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 All

Statements:

(a) Separate molecules by size.

(b) Separate molecules by charge.

(c) The stationary phase has a covalently bound group to which a protein in the mobile phase can bind.

(d) Uses a mobile phase and a stationary phase to separate proteins.

(e) The stationary phase contains cross-linked polymers with different pore sizes.

(f) Can separate molecules based on protein-lignand binding.

(g) The stationary phase may contain negatively or positively charged groups.
