Explosives Detection in Seawater on a Microchip

Abstract

Final report detailing effort to develop a capillary electrophoresis (CE) microchip sensor for the real-time, sensitive and selective detection of energetic explosives in seawater. Two primary issues are specifically addressed: 1) the development of new methods for enhancing the sensitivity to explosives via a pre-concentration step from seawater into the nonaqueous solvent, acetonitrile, and subsequent electrochemical detection following their microseparation on a microchip; and 2) methods for increasing the speed of analysis by employing the ultra-miniaturized solid phase extraction step that is coupled to a high speed microchip separation platform.
