Pharma information Zone: Difference between stationary phase and Mobile Phase in Chromatography

Stationary phase and the mobile phase is the two most important component of the chromatography. The main difference between the mobile phase and the stationary phase is as per their name; the Mobile phase moves into the column of the chromatography. While the stationary phase does not move with the column.

Following are the difference between the stationary phase and the mobile phase

Stationary Phase	Mobile Phase
Stationary phase does not move in chromatography technique.	Mobile phase move into the column of the chromatography technique.
The stationary phase can be solid or Liquid	The mobile phase can be liquid or gas or supercritical fluid.
Based on the stationary phase can be classified as column chromatography and planar chromatography	Based on the mobile phase chromatography can be classified as liquid chromatography and Gas Chromatography.
In some chromatography analyte reversibly react(Bind) with the stationary phase	In chromatography analyte or the stationary phase does not react with the mobile phase.
