Voltammetric analyzer AVA-3 uses one of electrochemical techniques, a stripping voltammetry at a rotating solid electrode.
The sensitivity of voltammetry is due to the use of a pre-concentration, or accumulation, step in which the analyte is accumulated at the electrode by either a faradaic (anodic or cathodic stripping) or non-faradaic (absorptive) process. The analytical signal is then generated by the subsequent voltammetric stripping step, where the voltage is swept, so as to remove the adsorbed analyte from the electrode. The current during this process is recorded as a function of voltage, and the area of the current wave produced (proportional to the charge passed) is measured.
