ALPHAGAZ™ Pure Gases (brand for lab gas)

Two grades, two levels of purity to meet all of your analytical application needs

Simpler choices

Choosing the right pure gas product for a particular instrument or application can be confusing.

Air Liquide has simplified gas selection by reducing the complex and confusing variety of available gas grades down to two levels of purity in our ALPHAGAZ™ product line.

  • Purity levels that ensure peak instrument performance
  • Optimal number of references
  • SMARTOP™ lever-activated cylinder valve included
  • Extensive inventory of equipment to protect purity and safely distribute all ALPHAGAZ™ pure

Available ALPHAGAZ™ grades

ALPHAGAZ™ 1, with guaranteed low impurity levels, eliminates the guesswork when choosing which grade of pure gas is correct for you application – one level of purity meets most requirements recommended for most carrier, purge and zero gases, making ALPHAGAZ™ 1 a cost-effective choice for just about any laboratory, analytic, process control and scientific research application.

ALPHAGAZ™ 2 pure gases provide ultra-high purity for the most critical laboratory, analytic and process control applications. These include petrochemicals for both laboratory and process control, secondary electronics and optoelectronics, scientific research and many others in which guaranteed low impurity levels are essential.

Cryogenic solutions are available for ALPHAGAZ™  pure argon, oxygen and nitrogen. These gases in cryogenic liquid form feature the same purity specifications as ALPHAGAZ™  1 and are useful when large volumes of gas are needed, such as nitrogen or argon used with ICP and FTIR instruments.

You can always depend on our quality - 

  • Guaranteed low level of critical impurities
  • Certificate of Conformity included with every cylinder
  • Guaranteed traceability with batch number per cylinder
