Air Liquide America Specialty Gases


SCOTT brand specialty gas mixtures have long been acknowledged worldwide as being the definitive standard for calibration accuracy for air monitoring and other environmental applications. These very same mixtures, produced using the same SCOTT technology, are now available from Air Liquide. Our ISO-certified laboratories follow strict procedures for preparation and analysis of SCOTT gas mixtures — ensuring products of the highest quality that are fully traceable to recognized metrology standards.

Through the legacy of Scott's heritage and having helped develop original EPA protocol gas mixtures guidelines with the US Environmental Protection Agency, Air Liquide maintains stature as the world's foremost authority and supplier of environmental calibration gas mixtures and EPA protocol gases. We remain actively involved in EPA calibration gas issues, and all five of our specialty gas facilities are registered participants of EPA’s Protocol Gas Verification Program (PGVP).
