Chromatography can separate a sample into three or more fractions each with a different protein of interest, whereas dialysis separates a sample into only two fractions. Chromatography can be used to purify precipitated proteins, whereas dialysis cannot. Chromatography can be used to separate molecules on the basis of charge, whereas dialysis cannot. All of the above are valid advantages.
