5.4.1
Cleaning the gold working electrode
Caution
Do not use any conventional sandpaper or glass-fiber brushes.
They could damage the electrode.
Note
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.
1
Moisten the gold working electrode and the SF 300 polishing
strip (see section 5.8 M
) 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.
