An Autonomous, On-Site Sampling / Analyzing System for Measuring Heavy Metal Ions in Ground Water
The autonomous system was developed in coordination with the development of new disposable Bismuth electrochemical sensors. Bismuth electrodes have the advantage of being more environmentally friendly than traditional Mercury drop electrodes, while maintaining similar sensitivity and other desirable characteristics. The system is approximately 8” W x 11” L (roughly the size of notebook paper) and about 3” deep. The small size and wireless computer interface gives the advantage of being portable for field use while not sacrificing portability for accuracy of measurement.
The developed sampling system was fully characterized for sampling and measuring functions in sequence for the analysis of heavy metals from both ground and surface water.
