Scott brand specialty gas mixtures from Air Liquide

Scott Brand Specialty Gas Mixtures from Air LiquideScott brand specialty gas mixtures have long been acknowledged worldwide as being the definitive standard for calibration accuracy. 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.

Our Scott brand calibration mixtures are analyzed against benchmark standards such as Standard Reference Materials (SRMs) and NIST-Traceable Reference Materials (NTRMs) obtained from the U.S. National Institute of Standards and Technology (NIST), or other recognized metrology institutes such as VSL (formerly NMi) in the Netherlands.

Customer Driven Accuracy and Traceability

Scott brand gas mixtures are generally differentiated by the degree of accuracy you require. They provide complementary levels of traceability, blend tolerance, process accuracy, analytical accuracy and other critical product parameters. With our gas and liquid standards, you have complete control over your calibration and process control standards because you select the class of mixture with the characteristics that are most appropriate for your use- without sacrificing performance and without paying for tighter specifications than your application requires. Air Liquide applies strict quality control procedures to raw materials as well as to finished products, ensuring that undesirable contaminants are not present.

Leading-edge blending processes and stringent analytical procedures, combined with knowledge acquired during almost 50 years of blending all types of mixtures, result in a product that will consistently be within your specified accuracy requirement.

Guaranteed Performance

Scott brand gas mixture classes comprise the world's most complete portfolio of specialty gas and liquid mixture products used in quantitative analysis and in process control applications. They establish an authoritative performance standard so that you never need to sacrifice dependability and mixture integrity (and value to your bottom line) for cost-effectiveness. Every gas mixture in each class is guaranteed to be within the specifications you ordered. Whether you need a high-accuracy master calibration standard that is traceable to a global reference standard, a reactive and complex process control mixture, or a simple two-component gas mixture for quick instrument checks, Air Liquide has a class of specialty gas or liquid mixtures that will perfectly match performance to your application needs.

Scott Brand Mixtures Product Offering

Air Liquide refuses to use low quality raw materials providing low purity levels. This is because increased impurities create application problems such as unidentified peaks on chromatographs. We therefore insist on using only the highest purity components available, and stock more than 800 high-purity components for use in making our gas and liquid standards.

The number of possible gas and liquid mixtures consisting of various components in varying concentrations is nearly infinite. In addition to the mixtures shown in this section, additional specialty mixtures are available, as are custom developed products for highly specialized applications. That said, even as the world leader in specialty gases, we sometimes encounter limitations that prevent us from making certain mixtures. Some are safety-related while most are just a matter of chemistry.
