Molecular Analyzer for Efficient Gas-phase Low-power INterrogation (MAEGLIN)
The MAEGLIN program intends to develop an ultra low power chemical analysis system for remote site detection and identification of explosives, chemical weapons, industrial toxins and pollutants, narcotics, and nuclear materials in the presence of significant background and interferents. Program goals include definitive chemical identification of species with an atomic mass < 500 atomic mass units (amu); a system footprint of less than or equal to 1.5 liters and weight of less than or equal to 7 kg, including sufficient power and, if necessary, consumables for two year operation with daily sample analysis; autonomous operation, including calibration; and a modular front end for gas, liquid and particulate aerosol, and bulk liquid and solid analysis.
In Phase 1 (covered by this solicitation) the program will be structured as three separate Thrust Areas:
- Collection – Low-power, reversible gas phase collection/storage/release technology. Modular front end sampling adaptor to add additional capability for liquid or particulate aerosol and/or bulk liquid and solid phase collection and volatilization.
- Separation – Low-power, non-destructive separation of chemical mixtures with a broad concentration range, potentially including the ability to “bleed off” all or part of the collected sample if desired. System will use minimal (preferably no) consumables.
- Identification – Low-power, high-accuracy identification of chemicals as pure compounds or low-count mixtures with a large library. System will use minimal (preferably no) consumables. Phase 2 (which will be covered by a separate solicitation) will focus on system integration and will culminate in a prototype demonstration.
