Scott Specialty Gases is a recognized world leader in the production of specialty gas mixtures (also called calibration gases or cylinder gases) that are engineered to meet a wide range of measurement and process control requirements. Leading-edge technology, including processes such as Acublend®, Aculife® and GravStat™ enable Scott to produce highly accurate and stable gas mixtures containing component concentrations as low as parts-per-billion. Our unique portfolio of seven distinctly different gas mixture classes allows you to perfectly match product performance to your application needs. Gas mixture classes are characterized by the degree of accuracy, level of traceability, blend tolerance, process accuracy, analytical accuracy and other critical parameters. With Scott gas mixtures and liquids, you have complete control over your calibration and process control standards—you can select the class of gas mixture with the characteristics that are most appropriate for your use, without sacrificing performance and without paying for tighter specifications than your application requires.

And, as you purchase your gas mixture online, you can also select the correct gas handling equipment from our Recommended Equipment suggestions - perfect for protecting your gas integrity.

Scott maintains the world's largest inventory of NIST-traceable reference materials (NTRMs) for several types of calibration gas mixtures. We also work with other metrological organizations throughout the world as well, including Van Swinden Laboratorium BV (formerly NMi). In addition, our Global Cross-Reference™ Services for low or high NOx, SO2, Btu measurement of natural gas, beverage-grade CO2 and applications enables government and industrial laboratories to effectively assess accuracy of their in-house analytical measurements via an independent outside party.
