You would like to carry out a Potensiostat analysis in your laboratory
A potentiostat is an electrochemical measuring instrument used to study the behaviour of a material subjected to electrochemical corrosion. It is a key tool in testing the performance of anti-corrosion coatings, particularly in wet, saline or chemical environments.
What is a potentiostat used for?
corrosion speed
the resistance of a coating to oxidation
the formation of passive layers
the kinetics of electrochemical reactions
Its use in anticorrosion coatings
In anticorrosion coatings, it is used for :
Testing the effectiveness of an anti-corrosion treatment
Drawing polarisation curves
Measuring corrosion current
Analyse polarisation resistance and electrochemical impedance (EIS)

FAQ
We analyse raw or treated metal parts, organic or metallic coatings deposited on a support, or standard test coupons. The sample must be suitable for an electrochemical cell.
Yes, the analysis can be carried out in different electrolytes (NaCl, acidic or basic media, custom solutions) to mimic your real industrial conditions.
The salt spray test is a global, visual and normative ageing test (ISO 9227), while the potentiostat provides numerical and dynamic data on electrochemical behaviour. The two approaches are complementary.
Yes, there are several standards governing electrochemical analysis:
- ASTM G5 / G59 / G102
- ISO 17475
- ISO 16773 (EIS)
We can adapt the protocols to your requirements.
