Choice of solvent(s) adapted to the wash steps?

It is necessary to take into consideration all compounds that are to be recovered. The solvents must have the highest possible affinity for the impurities and the lowest possible affinity for the compounds of interest, to avoid eluting them during washing. The pH can be varied to selectively eliminate Acidic, Basic or Neutral compounds.
