  We are experiencing a shift in Absorbance readings of our Organic
Salt which is apparently occuring during drying.
  We are purifying an organic salt with water, U.V. analysis after
washing is acceptable, but after air drying,.. we are failing tests
significantly,... and example partially wet material reading o.oo
at 260nm,.. after drying (in an apparently clean environment),..
we are reading o.o4 at 260, (failing)
   DOES ANYONE OUT THERE HAVE AN IDEA WHY THIS WOULD HAPPEN?
