Abstract :
This paper presents a portable two chip approach for detecting low concentrations of metals in water using stripping voltammetry. The measurement system comprises a disposable "Dipstick" incorporating a sensor ASIC (ASICTH), a "System Pod" incorporating a measurement ASIC (ASICM), and a Notebook PC AT compatible. The system is operated by connecting a "Dipstick" to the "System POD" and applying a drop of the water to be analyzed to the "Dipstick". The presence of the water is sensed and the assay starts automatically.
