Heavy metal detection combining stripping electrochemistry and piezoelectric sensor technology

Mercury and other toxic, heavy metals must be detected at part per billion levels in drinking water and environmental monitoring applications. No portable technology is presently capable of providing the required sensitivity, simplicity or reliability. Piezoelectric sensor technology and electrochemical technology have both offered sound approaches to the detection of these pollutants. Both exhibit limitations which prevent their widespread acceptance in water quality assurance and in environmental remediation.
