Dear All,
        I plan to make a big column of PVPP to clean the phenolic
compounds from a tobacco extract.  If  I want to save money on PVPP and
more importantly personal effort making columns, how should I clean the
column after use?
   Am I right to think that PVPP binds phenolics by hydrogen bonding?
Should I disupt phenolic compound binding with methanol?  or methanol
plus 10% acetic acid?

Regards, Mike
