Stationary phase: the retained part of a separation
A phase’s function in a separation is more informative than its physical appearance.

It is not always a solid
The stationary phase remains within the chromatographic system as the mobile phase moves through it. It may be a solid, a gel or a liquid retained on a support. Stationary phase and solid phase are therefore not exact synonyms.

Comparing methods in context
If reports use different columns, do not assume a compound will appear at the same time. Column description is part of the method. A resin used to assemble a peptide serves a different synthetic purpose from analytical separation.

Questions about this reference
Is every stationary phase a synthesis resin?
No. Chromatographic separation and supporting molecular construction are different roles.
