Gas Metrology Group

Welcome

The Gas Metrology Group is responsible for developing, critically evaluating, and applying techniques for the identification and measurement of gaseous species in atmospheres (urban, rural, and pristine) and process streams (automobile and stack). 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.  Measurement services are provided through the development of reference materials including NIST Traceable Reference Materials (NTRMs), Reference Materials (RMs), Standard Reference Materials (SRMs).
