One can probably safely assume that the solvent/combo in question is a common solvent used in extraction so that narrows down the choices of what can be done.
First check the pH of the liquid(could be standard or modified a/b if no solvent smell is detected.)
If not an a/b, Just pour off the solvent and evap some on a watchglass and see what materializes.
If Pinwheels, then evap all the solvent and collect the feedstock! Rehit the GUPs with alky until all is collected.
The pillmass should be spread out and completely dried to remove any ???solvent??? residual after pouring off solvent.
Either use alky to extract the pillmass and determine after evap if further cleaning is necessary(more than likely).
Or just A/B the Pillmass to recover what's recoverable.
Further clean-up will need to be considered after getting the raw feedstock away from the binders/crap, most likely.
But you'll be relatively homefree.
If there is no solvent smell at all coming from the liquid/Pillmass assume an a/b was being done and check the pH. Finish the a/b.
Could be h2o too if non-DMF pills were used. If so the initial sample evap will tell the tale.
