      It would be possible to separate the alcohol from other substances in
      a chromatagraph column although it would also be extremely hard. One
      of the basic principles of the chromatograph column is the time that
      a
      particular substance can move through the column. This means that all
      substances will go through the column just at different stages. You
      could possibly collect at only the time alcohol will be released but
      that means you would have to be at the column at that exact time and
      you would have to work out the time it would come through.
      There are better chromatography devices that will separate the
      substances more effectively one is the gas liquid chromatography.
      This
      uses a long tube about 1 meter (for small amounts of test liquids).
      The tube is filled with a porous substance which slows down the
      liquids or gases according to there molecular weight.
      These devices are to small for large quantaties of alcohol to pass
      through them and effectively separate the different components.
      You could use chromatography for alcohol separation but you would
      probably end up collecting 5 mil amounts of alcohol every half hour
      or
      something like that so personally i would stick to distillation or if
      you want better ethanol separation vacume distillation which is also
      riddled with troubles.
