Key Stage 4
Meaning
The stationary phase refers to the paper used in a chromatography experiment.
About the Stationary Phase
- During a chromatography experiment chemicals in a sample experience forces of attraction to the chromatography paper and the solvent being used. The stationary phase is caused by the force of attraction to the chromatography paper which acts to hold the chemical in the same place (stationary).
