3 grades, 2 purity ranges for your analytical application needs
Simplify your gas selection
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 2 levels of purity as represented in our ALPHAGAZTM product line. We focus on the critical impurities that affect the performance of the instrument and application used, so it is easy to match gases with the requirements of your equipment.
An Air Liquide research and development team surveyed major analytical instrument manufacturers to determine the recommended gas purity for their instrumentation. Our findings indicated that two basic ranges for gas purity are necessary to ensure optimal performance of analytical instruments in most applications. Discover the ALPHAGAZTM grades for 2 levels of purity according to your needs:
Most analytic and process control applications
Designed for analysis from percentage to ppm
Air, Argon, Helium, Hydrogen, Nitrogen, Oxygen
ICP and FTIR instruments
Argon, Helium, Nitrogen
99.9998 (He, H2, N2)
Laboratory, analytic and process control applications requiring ultra-high-purity
To increase safety and ease of use, all AlphagazTM cylinders come with a Scandina cap and most of them have a SMARTOP™ valve, which includes an on/off lever, a gauge and a residual pressure valve.Discover the benefits of SMARTOP™.
