Sylph is an ultra-compact, high-performance gas chromatograph for onsite chemical analysis of space and terrestrial environments. Unlike conventional gas chromatographs that are as large as dormitory refrigerators, the palm-sized Sylph weighs only about 2 kg (4.4 lb.) and is operable on mobile battery power – which makes gas chromatography accessible anywhere. Powered by our proprietary “Ball Surface Acoustic Wave (SAW) Sensor” (internationally patented), Sylph is as sensitive in detecting chemicals as state-of-the-art desktop gas chromatographs, measuring polar hydrocarbons down to the ppb order. Developed in collaboration with the Japan Aerospace Exploration Agency (JAXA).
