How Separation Works in Column Chromatography Methods

How Separation Works in Column Chromatography Methods

By Dr. Jessica Torres | August 29, 2016

Separation in column chromatography relies on differences. Molecules vary in size, charge, polarity, and solubility. We leverage these differences to distribute molecules between a stationary phase and a mobile phase. But because molecules are so different, it’s not possible to have a single method that works for all. In my previous article I discussed the…
