Q

Chromatography

A

The mobile phase which is the solvent, moves through the stationary phase. The stationary phase is a high surface area or liquid coated onto a solid support. It always stays still. The mobile phase moves through and carries a sample (solute) over the stationary phase, depending on intermolecular forces. This makes different components move at different rates and separate them
