To polish the SenCell:
1. Shake the diamond slurry (700001955) thoroughly before use.
2. Rinse the polishing disk with demi-water before applying the diamond slurry.
3. Apply a small amount (a few drops is sufficient) of slurry on the wetted polishing disk, and
polish the electrode with a figure-eight motion for about one minute. Apply only gentle
pressure.
4. Clean the electrode with an ethanol-wetted tissue and check the surface visually. Repeat
the procedure if necessary.
5. Reassemble the detector cell.
6. Clean the polishing disk with demi-water.
7. Store the polishing disk in its plastic bag.
