Free-Form Dual Comb Technology Improves Gas Leak Detection

Facebook X LinkedIn Email
GAITHERSBURG, Md., Oct. 22, 2024 — A smart dual-comb spectroscopy (DCS) technique, from the scientists at the National Institute of Standards and Technology (NIST), detects gases and other substances with more speed and sensitivity than traditional dual-comb methods. The new, free-form DCS method quickly identifies the most information-rich parts of a sample’s fingerprint, making detection and measurement of substances more efficient. In the future, it could be key to locating small leaks or emissions that might contribute to climate change and otherwise go unnoticed. DCS is a high-resolution form of...Read full article
