Dr. Christine Connolly, UK Correspondent, [email protected]

Nondispersive infrared (NDIR) absorption spectroscopy detects and measures various gases by their characteristic IR absorption bands. The technique is not new, but its application to climate studies, biofuels and geological research makes it a hot topic, and a number of companies have developed small, rugged, high-precision instruments especially for environmental and process monitoring. Since 1957, NDIR instrumentation at Mauna Loa Observatory on the Big Island of Hawaii has continuously measured carbon dioxide levels in the ambient air. Located far from pollution sources, and sampling...Read full article
