The National Institute of Standards and Technology (NIST) of the United States Department of Commerce has renewed its exclusive contract with Scott Specialty Gases to produce numerous types of gas mixtures in a variety of low concentration levels. The gas mixtures will be analyzed by NIST before being certified as Standard reference materials (SRMs). Scott is currently the sole-source producer of SRM candidates.

NIST will resell the majority of Scott-produced SRMs as reference materials for calibrating instruments used for monitoring environmental pollution. The U.S. Environmental Protection Agency (EPA), for example, mandates that industries must calibrate Continuous Emission Monitoring Systems (CEMS) using protocol gas mixtures that have been prepared using, or are traceable to, NIST SRMs. This ensures accurate emission measurements are made and reported. NIST gaseous SRMs are the most accurate standards available in the world and are the 'yardstick' by which all other gas mixtures are measured.
