Micro-Chemical Sensors for In-Situ Monitoring and Characterization of Volatile Contaminants
Page • This website provides information about Sandia's Laboratory Directed Research and Development (LDRD) project that investigates and develops micro-chemical sensors for in-situ monitoring of subsurface contaminants. Description Traditional methods for monitoring sites that may be contaminated with toxic chemicals can be expensive, time consuming, and misrepresentative of in-situ conditions. A few...
