美國斯科特特種氣體公司（Scott Specialty Gases）? ?
斯科特特種氣體公司（Scott Specialty Gases）簡稱ScottGas，建立于1960年，早期是以環境監測和有關污染物研究的成果而形成異軍突起的形象。現今，ScottGas是一個在美國和歐洲設廠生產的國際性特種氣體生產者和供應商。主要產品是用于研究工作的高純氣，標準氣，混合氣，電子氣，醫療氣體。ScottGas還提供高壓氣瓶，閥件，調壓閥，氣柜，氣路系統（可定做）。
ScottGas總部位于美國Philadelphia, Pennsylvania，在美國和歐洲有9個制造廠。和美國環保局EPA及NIST有長期合作歷史，共同開發了多種專用氣體。
ScottGas是美國環保局(EPA)指定獨家生產的標準氣體的廠家：其中包括供標準傳遞的二級標準（RATA?級）和一般應用的標準氣體（ComlianceTM級）。
例如，按照EPA的方法3A,6C,7E,10,10A,10B,15,15A,16,16A, 16B,18,20,21,23,25A,25B, 25C, 25D, 25E所規定的，提供2組分標準氣43種，3組分標氣33種，4組分標氣37種和5組分標準氣體6種。
其他環境監測用的氣體氦包括：空氣中或者N2中的NH3瓶裝標準氣：1-9.9ppm,10-9999ppm,1-10%；酸雨測定用的零點空氣和氮。；氮中HCl: 0-25ppm, 25.1-5000ppm, 5001-5%；氮中H2S:20-99ppm,100-300ppm；CEM標氣和零點氣；各種烴分析的色譜標準氣；天然氣的標定氣；發動機排氣、垃圾焚燒等有毒氣體分析用的標準氣。
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?
Supply Chain Management. eScott includes online inventory, product expiration notification, customized
product FOLIOs?, 3-year cylinder history reports, online Certificates of Accuracy and MSDS documentation.
The Scott's Solutions Center provides a toll-free hotline (800-21-SCOTT) where customers can get fast,
accurate answers and expert recommendations from engineers who understand complex specialty gas
applications.

Headquartered in the Plumsteadville, near Philadelphia, Pennsylvania, Scott maintains numerous ISO 9001-
2000 certified manufacturing facilities throughout North America and in Europe to provide on-time
