ALPHAGAZ TM

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.
