Bringing the best for analysis and cryogenic needs
ALPHAGAZ?, premium specialty gases for analytical applications
With over 30 years experience in the analytical field, our ALPHAGAZ? products offer undisputable accuracy and traceability, with a complete yet simple range of the most commonly requested purity levels for pure gases.
- ALPHAGAZ? 1 pure gases are ideal for most analytic and process control applications, for the accuracy of analysis from % to 10 ppm
- ALPHAGAZ? 2 pure gases exhibit the absolute lowest impurity levels available in the industry, for high accuracy of analysis ppm to ppb
All our products are made to guarantee high accuracy and repeatability to your analysis. ALPHAGAZ? pure gases cylinders benefit from our exclusive SMARTOP? valve, a residual pressure valve equipped with an on/off lever and a permanent pressure gauge. Our customer service teams are easy-to-access and totally engaged, ready to support you from assessing the right product to using it in the lab.
We also offer a complete and dedicated range of gas handling equipment (including regulators, manifolds etc.).?
Calibration gas mixtures
Leveraging on decades of expertise with specialty gases, Air Liquide addresses the mixture markets with high purity calibration mixtures, available on catalogue or designed on request for specific requirements. Our products combine from 2 to 40 components, with accuracy ranging from % to ppb, covering a high range of analytical needs, more especially for the automotive, environment and oil industries.
All our mixtures, including ALPHAGAZ?,?Scott? and CALGAZ?唔…啊 手指 出去 ranges, are produced worldwide with standardized in-house mixing units and delivered with top certificates.

Mastering extreme cold
We also supply customized solutions in mechanical cold production, liquefaction, storage and distribution of cryogenic fluids at very low temperatures:
- HELIAL? helium refrigerators can provide cooling power from 100 W to 1 kW at 4.5K for various applications (synchrotron,?cyclotron, accelerator,?simulation chamber?etc.)
- HELIAL? helium liquefiers can provide liquid helium at 4.5K at flow rates varying from 15 to 300 L/H for applications (superconductivity, nanotechnology,?biology, quantum physics etc.)
- The HYLIAL? range focuses on hydrogen liquefaction with an helium loop that can supply between 600 and 1,500 L/H of liquid hydrogen
- Turbo-Brayton cryogenic systems ensure refrigeration and liquefaction from 25K to 200K
