As well as giving useful information about adsorption and redox processes in natural water samples, voltammetry is a powerful tool for measuring sub-ppb concentrations of some 20 elements (metals and metalloids) as well as electrochemically-active organic compounds.
Our PC-controlled voltammetry system (Metrohm model 757VA) is coupled to a pump unit (Model 772) and autosampler (Model 813) used in

titration mode, it is ideally suited to the determination of the chemical speciation of trace metals in seawater, which is one of the fundamental factors affecting their geochemical cycling and biological availability.
