Specialty Gas CatalogMolecules that Matter

ALPHAGAZ Pures, SCOTT Mixtures and Equipment | 2009 Edition

As a leading world supplier of specialty and industrial gases, Air Liquide is all about molecules that matterOur technologies are carefully engineered to provide customers with meticulously analyzed measures of certain molecules in the form of pure or mixed gases and liquids. These molecules are in turn used as raw materials or end products in themselves, as is often the case in healthcare or food and beverage processing. Other times the molecules we provide are used to measure or test for the presence of other molecules, as in applications such as environmental monitoring, homeland security or process control. Our focus however, goes well beyond the refining and selling of molecules. It includes providing definable value that can be measured at the bottom line. About one third of Air Liquides product sales can be linked directly to applications that are helping to preserve our environment or ensure human safety. Other Air Liquide products and services involve helping our many customers keep pace with a challenging global economyby empowering them to improve efficiencies without sacrificing end product quality or analytical accuracy. Our commitment to safety, technology and innovation has kept Air Liquide at the forefront of the high-tech business of specialty and industrial gases for more than 100 years. Our presence of over 43,000 employees in 75 countries enables us to leverage the resources of a truly global enterprise with powerful, personalized service from our localized, customer-focused teams. Combined with innovative products and services, we believe this to be a winning formula that transforms molecules that matter into greater customer satisfaction, efficiency, growth and successplus a safer and cleaner environment for us all.

PackagingCylinders for Every Application

Air Liquide provides a wide variety of cylinders selected to meet specific customer needs. In that we produce many gases with widely varying chemical characteristics, appropriate package offerings must be based on several key criteria. Safety The safety of each and every customer, as well as that of those who handle or transport our products, is of the utmost importance. Selection of the correct container and the proper valve is determined by guidelines from CGA, DOT and TC, as well as our own extensive experience and expertise. Stability Since specialty gases can be corrosive or reactive in nature, we carefully match cylinder and valve types in order to protect the integrity of the gas. To ensure gas mixture stability, reactive gases are only provided in cylinders treated with our exclusive suite of ACULIFE cylinder inerting processes see page 84 for more information. Customer Convenience For most gases, the choice of container depends upon your application requirements. We offer many different cylinders, as well as multi-cylinder packs, tube trailers or even cryogenic liquid containers for atmospheric and helium pure gases.

PuresAnd Other Support Gases

Air Liquide is one of the largest producers of pure gases globally. Because we produce most of these gases ourselves, we closely control the consistency and quality of each gas. Our customers can be sure of getting the best quality possible for every pure gas we deliver. We offer three grades of ALPHAGAZ pure products with specifications that meet typical application requirements and enable you to reduce the number of various pure gas cylinders you must keep on site. Three grades of CHEMGAZ products standardize grade selections for process gases as well as simplify your ordering process. Three electronic grades support a wide range of semiconductor, optoelectronic and other electronic applications, while our application-specific products provide additional application versatility.

PURES AND OTHER SUPPORT GASESALPHAGAZ Pure Gases

ALPHAGAZ Pure GasesChoosing the right gas products for a particular analytical instrument and application can be confusing. Air Liquide has simplified gas selection by reducing the complex and confusing matrix of available gas grades down to two levels of purity as represented in our ALPHAGAZ product line. Instead of focusing on the total purity of the gas, we set limits on the critical impurities that affect the performance of the instrument and application used.

Three Grades, Two Purity RangesAn Air Liquide research and development team surveyed major analytical instrument manufacturers to determine the recommended gas purity for their instrumentation. Studies were then conducted on many of these instruments to determine the effect of varying levels of impurities on their performance. Our findings indicated that two basic ranges for gas purity are necessary to ensure optimal performance of analytical instruments in most applications. ALPHAGAZ 2: The Highest Purity Level Possible ALPHAGAZ 2 products exhibit the absolute lowest impurity levels available in the industry, making them the best choice for laboratory, analytic and process control applications where uncompromised ultra-high-purity is needed. ALPHAGAZ 1: One Convenient Grade for Many Applications ALPHAGAZ 1 products exceed purity recommendations of most laboratory instrument manufacturers, making them an obvious choice for all-around use in the laboratory. Because they provide guaranteed low impurity levels, ALPHAGAZ 1 pures are ideal for most analytic and process control applications, including petrochemical, secondary electronics and optoelectronics as well as scientific research and many other applications. ALPHAGAZ 1000: Cryogenic Solutions ALPHAGAZ 1000 provides the same specifications as ALPHAGAZ 1, but is offered for those applications requiring cryogenic liquid argon, nitrogen and helium. Since large volumes of gaseous nitrogen or argon are needed for ICP and FTIR instruments, cryogenic supplies can be better suited than cylinders of compressed gas to fill this need. Liquid helium is often used to cool magnets in instruments such as NMR spectrophotometers.

Our customers get the best quality possible for every pure gas we deliver
