Voltammetric applications

Traces of heavy metals in basic chemicals
Heavy metal ions present in the basic chemicals can cause interference during the production process. For this reason, a purity check is carried out when goods are received.

On the other hand, in the electroplating industry large quantities of basic chemicals are used and as a result sizeable quantities of heavy metals are introduced into the production process. This contamination needs to be prevented as far as possible right at the start of the production chain, to avoid the need to remove it at great cost later. Such checks are a classic application of voltammetry.
