However - I do have a recollection of a similar type of sample prep which resulted in substantial column bleed after the fact, presumably due to the high acid concentrations involved that made its way into the pentane. I do not wish to repeat that result and risk damage to my new column.
I am considering adding base after solubilizing the material to gain a less acidic solution prior to solvent extraction - and hoping that it does not cause the re-precipitation of the material.
Thought I would see if there are alternate ideas out there before proceeding.
