5.4.1 Cleaning the gold working electrode
NOTE
Do not use any conventional sandpaper or glass-fiber brushes. They
could damage the electrode.
#
1 Moisten the gold working electrode and the SF 300 polishing
strip (see section 5.8 M
AINTENANCE EQUIPMENT AND
REPLACEMENT PARTS
) with deionized water.
2 Using the rough side of the wet SF 300 polishing strip, polish
off any contamination from the gold working electrode using
light pressure.
3 Rinse the sensor head with deionized water.
Cleaning the gold working electrode may already be
sufficient to enable the sensor to be calibrated again. For
safety, however, we recommend to also clean the silver
counter electrode (see section 5.4.2) and to use a new
membrane cap afterwards.
