Fast GC for Space Applications Based on PIES Technology, Phase I

Development of a novel analytical instrument which combines the advantages of fast GC and a detector capable of identifying species is proposed. Experiments in the limited-space environment require from a GC system maximum productivity and universality with minimal resource consumption. A combination of a short-column fast-chromatographic separation technique with a low-power-consumption miniature detector capable of identifying unknown species would be an ideal instrument for flight analysis. The proposed instrument will employ the technology of Penning Ionization Electron Spectroscopy in plasma (PIES) which provides an excellent opportunity for the development of a fast-GC/PIES combination that satisfies these requirements. A new micro-PIES detector is proposed that uses continuous flowing afterglow discharge cell design enabling the measurement of PIES spectra in continuous flow at atmospheric pressure of the carrier gas. PIES spectra for permanent gases will be recorded in Phase I by a micro-PIES detector prototype. In Phase II of the project, a commercially viable micro-PIES detector and an analytical device combining fast GC and the micro-PIES detector, will be developed.

Portable analytical devices which would provide fast and sensitive identification of analytes are required in the majority of the GC detection fields. The advantages of the proposed technology are in the optimal combination of the small size and weight, simplicity and ruggedness of the design, and the ability to identify unknown species. Such technologies are required for various industrial, forensic, military, security, research, environmental and educational needs. Some specific applications include microelectronics; airport security; weapons drug, alcohol, and other contraband detection; landmine detection; individual/consumer applications and hazardous waste treatment, among others.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
