In particular, tagging spectroscopy works by weakly attaching a reporter ‘tag’ — typically an atom of a noble gas or an inert molecule such as nitrogen (N 2) — to the molecule being examined.

HKUST, SUSTech, and NCAMS researchers reveal nitrogen’s dominant role in global organic aerosol absorption Peer-Reviewed Publication Hong Kong University of Science and Technology ...

Laser absorption spectroscopy allows checking for leaking caps or valves, as in the case of kegs, and monitoring N2, CO2 and O2 presence in different types of closed products.

The possibility of enhanced nitrogen absorption was particularly intriguing to tea experts Wei Xin and Wenxin Tang at Fujian Agriculture and Forestry University in China because tea plants rely ...
