Voltammetry and polarography analysis system Metrohm

Voltammetry instruments and polarographs are favorably priced and compact, yet great in their detection capabilities.
- With voltammetry you can analyze trace elements in water, environmental samples or ultrapure chemicals!
- With the Cyclic Voltammetric Stripping technique (CVS) the analysis of organic additives in plating baths can be carried out easily and accurately.

Convincing applications
1) Apart from the determination of the total concentration, voltammetry allows to distinguish the different oxidation stages of metal ions or differentiate between free and bound metal ions as well as to specify the biological availability of heavy metals. VA instrument can also be used in mobile laboratories for environmental analysis.

2) Not only metals but also various organic compounds can be determined by voltammetry, but also some special anions. The determination of environmentally relevant anions like cyanide, sulfide, nitrite or nitrate is particularly interesting.

Automation makes work easier, increases sample throughputs and provides more exact results. For example, the CVS determination of organic additives in the plating industry can be carried out manually, partly automated or fully automated using the 838 Advanced Sample Processor.
