Measuring trace metals in water, soil and food has always been a vital part of modern environmental monitoring. Voltammetry offers an internationally accepted alternative to laboratory analysis. Avance Aqua provides better on-site characterisation, with pollution hot spots and contamination sources more easily identified.
In voltammetry metals are drawn onto the working electrode when a specific voltage is applied to the water sample under test. When a stripping voltage is applied, the metals return to the sample solution, generating a small current. Each metal has a specific voltage at which it returns to solution. So the metal is identified by its stripping voltage, and the current generated is proportional to the concentration of metal in the sample.
