Cause 2: induced gases
Change the position of your gas inlet.
Induced gas bubbles which are piped by close to the hydrogen electrode can disturb
the measurements and lead to fluctuating potentials.
Cause 3: potentiostat or measuring device
Check your measuring device.
If you measure in low conductive electrolytes potentiostats and measuring
devices come fast to their limits.
Deposits (e.g. red or brown) on the electrode
The hydrogen electrode is contaminated and a mixed potential is set.
Check the runtime of the hydrogen supply. If necessary, the hydrogen cartridge
must be replaced (4. Maintenance).
Wipe the electrode with a cloth or clean it in 1 mol/l nitric acid and rinse it with
distilled water.
If necessary, you can carry out a complete cleaning like described in
4. Maintenance.
If that is not successful, the electrode is so badly contaminated that we suggest a
new purchase.
