FAQs

Can platinum electrode tips be polished

Metrohm does not recommend any mechanical treatment of platinum RDEs, e.g., by polishing with aluminum oxide!
Can Metrohm polish platinum electrode tips?

For logistical and technical reasons, Metrohm cannot offer a polishing service for used platinum electrode tips.
How do I clean my platinum electrode tip?

A contaminated platinum electrode tip can be conditioned in VMS or diluted H₂SO₄.

To clean a contaminated platinum electrode tip, it can be stored for approx. 60 minutes in c(NaOH) = 1 mol/L. Afterwards, the electrode should be well rinsed with isopropanol and deionized water.
The platinum electrode tip may not be treated in an ultrasonic bath.
The electrode surface of the platinum electrode tip is coated with a foreign metal (Cu, Sn, etc.). What can I do?

The platinum electrode tip can be immersed for a few seconds in concentrated nitric acid to oxidize a metal coating which has accidentally been applied. If after another measurement foreign metal should be found on the surface again, then the method parameters and electrode connectors need to be checked.
Can the platinum electrode tip be treated in an ultrasonic bath?

No, the platinum electrode tip may not be treated in an ultrasonic bath. This will irreversibly damage the electrode.
