Adsorption and desorption terminology

[kenhung123]

Is it true I cannot use adsorption by itself? Because it can be adsorption onto stationary phase (slowing down movement) or adsorption onto mobile phase (speeding up movement)

Desorption from stationary=adsorption into mobile phase=faster movement of component?

[physics]

yes and higher Rf value.

[crayolé]

I've always said it adsorption onto the stationary phase and desorption back into the mobile phase

[kenhung123]

Also does the solvent move proportionally to the components in paper chromatography? Does the Rf value change with changing solvent front distances?

[crayolé]

Yes it does ;]
Since the Rf value is measured using the solvent front
