Established in 1960, Scott Specialty Gases was first known for its work in atmospheric monitoring and other pollution related studies. Today, Scott is the leading international producer and supplier of mixed and pure specialty gases as well as high-performance gas handling equipment and specialty gas delivery systems. Ten distinct classes of gas mixtures are available to meet virtually any application needs for industrial, scientific and medical industries. Scott specializes in developing calibration gas mixtures for environmental monitoring applications, maintains a close working relationship with the U.S. Environmental Protection Agency and is the world’s largest producer of EPA protocol gases. Low-ppm NO protocols, low-ppm NO/CO blends and Title V Ammonia Calibration Standards are Scott exclusives. Custom gas mixtures can be engineered to meet any unique specialty gas application requirement.

Scott Specialty Gases has over 40 years of experience developing leading-edge technology such as
Acublend®, Aculife® and GravStat™ that facilitate production of highly accurate and stable gas mixtures
containing component concentrations as low as parts-per-billion. Scott maintains the world’s largest
inventory of NIST-traceable reference materials (NTRMs) and often works with various metrological
institutions, including Van Swinden Laboratorium BV (formerly NMi). Scott also maintains a Global Cross-
Reference™ Service (proficiency testing) for low or high NOx, SO2, Btu measurement of natural gas,
beverage-grade CO2 and others. The service enables government and industrial laboratories to effectively
assess accuracy of their in-house analytical measurements via an independent party.

SCOTTY® Transportables, the industry’s largest selling brand of nonreturnable products, provide high-
purity and accurate calibration gases in a variety of nonreturnable gas cylinder sizes and volumes. High
reliability and convenient size make them a cost-effective alternative to returnable, high-pressure gas
cylinders whenever portability or limited gas quantities are needed. SCOTTY Transportables permit
substantial cost savings by eliminating gas cylinder rental and two-way shipping charges associated with
refillable cylinders. Small gas cylinder sizes also allow users to purchase small amounts of specialty
gas.

Scott Specialty Gases combines technology-driven products with value-added services to help specialty gas
users take cost out of business. Here at scottgas.com we provide customers with powerful eTools including
online purchasing of all specialty gases and gas handling equipment, electronic invoicing and eScott®
