O2, N2, CO2, He, Ar…
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. And, we offer many grades of pure gas products for any application.
ALPHAGAZ™ Pure Gases
Choosing 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 specialty pure gas, we set limits on the critical impurities that affect the performance of the instrument and application used.
Three Grades, Two Purity Ranges
An 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™ 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.
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.
APHAGAZ™ 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.
Application-Specific Grades of Pure Gases
Air Liquide also offers application-specific pure gases that have long been accepted as a standard in the industry, and provide additional application versatility.
