Chromatography usually involves two different phases. What names are given to these two phases?

Chromatography is an experimental technique that we can use to separate components of a mixture. To perform a chromatography experiment, we place our sample on the stationary phase, which could be something like a piece of paper or a TLC plate or something more complicated for other forms of chromatography. Then, we place our sample that’s on the stationary phase in a container filled with the mobile phase, which can be water or some other kind of solvent. As the mobile phase moves up the stationary phase, interactions between the sample in the stationary phase and the sample in the mobile phase will cause the sample to be separated into the components that make it up.

So the names of the two phases involved in chromatography experiments are mobile and stationary.
