- A chaser solvent or pusher solvent is sometimes used to help blast your compound off the surface of the packing material. It should have a tremendously high boiling point relative to what you were fractionating. After you ve collected most of one fraction, some of this material is left on the column.chempedia.info/info/distillation_chaser_solvent/
