The Gas Sensing Metrology Group (GSMG) of the Chemical Sciences Division is responsible for developing, critically evaluating, and applying techniques for the identification and measurement of gaseous species. The group applies these techniques with the certification of gas standards in support of industries responding to U.S. and state regulations and fairness in trade issues. 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). The GSMG needs to purchase a gas chromatograph with a flame ionization detector and pulsed discharge helium ionization detector in order to support the development of SRMs, NTRMs as well as for standards used for international comparisons and other certified compress gases.
