Answer #1

There are two major components in the chromatography experiment: the solvent system (mobile phase) and the paper (stationary phase).

The mobile phase flows through the stationary phase and carries the components of the mixture with it. Different components travel at different rates. We'll look at the reasons for this further down the page.

In paper chromatography, the stationary phase is a very uniform absorbent paper. The mobile phase is a suitable liquid solvent or mixture of solvents.
