Description

Ultimately, there is a need for miniature analytical instrumentation that is hand-portable or used for remote in-situ monitoring and includes the necessary analysis processes to provide quantitative analysis of multiple targets with minimal possibilities of interference. Ideally, these instruments will have analysis times of seconds to minutes and be relatively inexpensive so that they can be massively deployed. One approach for this analytical instrumentation for liquid phase analysis is to develop microfabricated fluidic devices with appropriate functionality. Over the past decade, significant advances have been made in this area, particularly for the analysis of biomolecules, but further research and development ... continued below

Description

Ultimately, there is a need for miniature analytical instrumentation that is hand-portable or used for remote in-situ monitoring and includes the necessary analysis processes to provide quantitative analysis of multiple targets with minimal possibilities of interference. Ideally, these instruments will have analysis times of seconds to minutes and be relatively inexpensive so that they can be massively deployed. One approach for this analytical instrumentation for liquid phase analysis is to develop microfabricated fluidic devices with appropriate functionality. Over the past decade, significant advances have been made in this area, particularly for the analysis of biomolecules, but further research and development is needed to produce robust, miniature instruments capable of analyzing environmental samples. This proposal attempts to further the development of these liquid phase analysis devices by providing low- and high-pressure pumps that can be easily incorporated into microfluidic devices. Such devices would be capable of executing well-recognized characterization methodologies that include sample filtering to exclude particulate matter, concentration of target molecules by solid phase extraction, and target analysis by liquid chromatography. If these capabilities were integrated into a miniature platform, a very powerful analytical tool would be available for EM to use as an emplaced sensor for assessing subsurface contaminant transport, performing in-situ wide area site remediation, and monitoring in a variety scenarios. A key component of these instruments is a robust, high performance, low cost, low power pump, and this proposal sets out to develop and optimize such a pump.
