Gas Sensing Metrology Group

About

The Gas Sensing Metrology Group (GSMG) conducts measurement science research that underpins the identification and quantification of gas species.  The GSMG develops, critically evaluates, and applies techniques including gas chromatography, mass spectrometry, laser spectroscopy and other optical methods for the identification and measurement of gaseous species in atmospheres and process streams and develops and certifies gas mixture Standard Reference Materials®, industry-produced NIST Traceable Reference Materials™, and Standard Reference Instruments (SRI).  The group applies these techniques to certification of gas standards in support of industries responding to U.S. and state regulations, environmental concerns, fairness in trade issues, and global climate change.  The primary concern is to provide the infrastructure for high-quality, traceable gas measurements, allowing better decision-making by industry, regulators, government officials, research scientists, and the public.
