Remove any exterior contamination from Cathode Solution Cell with tissue paper and
acetone being careful not to damage the platinum wires and screen on the outside of the
cell.
Fill the Cathode Cell with acetone and stopper the inlet joint. Shake the unit until any dirt
is removed. This should be repeated several times. Pour out and discard acetone.
Wash the outer surface with acetone.
Pour approximately 5 ml of acid into the Cathode Solution Cell.
Place the cell in a 50 ml beaker and fill the beaker with acid to the same level as is in the
cell. Secure the Cathode Solution Cell so that it will not fall over. Allow the cell to remain
in the solution overnight.
After the cell has stood overnight, discard the nitric acid in the cell, and rinse the inside
and outside of the cell with running tap water until the yellow color disappears.
Place distilled water in the cell and place it in a 400 ml beaker filed with distilled water.
Place the beaker on a hot plate and bring the water to a slow boil for at least one hour.
Repeat this operation until there is no coloration of the water.
Remove the Cathode Solution Cell from the water and fill it with acetone to overflowing,
flooding the outside of the cell as well. Shake the cell, dump out the acetone, then refill
and repeat.
Dry the cell with a forced air dryer.
NOTE: Do not use compressed air as the increased pressure could damage the compo-
nents.
Place the entire assembly in a laboratory oven and continue to dry it for several hours at
120º F.
