Voltammetry is characterized by its high sensitivity, its insensitiveness against interferences caused by high concentrations of dissolved solids, and its low costs of purchase and operation.

What’s more, it can be used for speciation analysis, e.g., to differentiate between different oxidation states of elements. With more than half a century of experience in voltammetry, we offer you not only powerful measuring systems, but also a wide range of applications and competent support.
