Answer
Mobile phase
Explanation
The mobile phase is the phase that moves through the stationary phase and carries the sample with it, facilitating the separation of components based on their interactions with both phases.
Common mistake
Confusing Phases
Students often confuse the roles of stationary and mobile phases in chromatography, thinking both are the same.
Remember that the stationary phase is the substance that does not move, while the mobile phase is the solvent that carries the mixture through the stationary phase.
