In Situ Isotope Analyzer for Lunar and Planetary Science

We propose the development of a new instrumentation based on a concept for trace-gas and isotope analysis that utilizes a priority hollow fiber as a low-volume, compact gas cell. An analyte is drawn into the fiber, which has a reflective inner coating that guides a tunable laser beam to a detector. There is near unity overlap between the laser beam and the gas sample, leading to a highly sensitive system with an ultra-compact size. In Phase II, a prototype analyzer will be assembled, and measurements conducted to prove the performance of the novel instrument. The isotope analyzer will also be combined with a prototype sampling front-end to demonstrate a complete system in simulated conditions. A path towards NASA insertion for both lunar and other planetary applications will be developed. In parallel we will demonstrate the technology for commercial applications, targeting markets where the sensor can effectively fill a growing need for robust field-capable isotopic analyzers.
