Premium range of specialty pure gases & mixtures for analytical applications.

ALPHAGAZTM is a portfolio of ultra-high purity specialty gases and mixtures to provide research institutions reliability and consistency that meets the most stringent requirements of analytical applications.

ALPHAGAZ™ Pure Gases

The Simple Solution to Enhance Your Analytical Performance

ALPHAGAZTM pure gases maximize the quality and reliability of your analysis and the efficiency of your analysers. We offer a choice of two purities for helium, argon, nitrogen, hydrogen, air and oxygen available in gaseous form or liquid form:

  • ALPHAGAZTM 1: the commitment to quality for % to 10 ppm analysis. It 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 ALPHAGAZTM 1 a cost-effective choice for just about any laboratory, analytic, process control and scientific research application.
  • ALPHAGAZTM 2: the commitment to highest purity for high precision ppm to ppb analysis. It provides ultra-high purity for the most critical laboratory, analytic and process control applications. These include petrochemicals for both laboratory and process control, electronics and optoelectronics, scientific research and many others in which guaranteed low impurity levels are essential.

Cryogenic solutions are also available for ALPHAGAZTM pure argon, helium and nitrogen. These gases in cryogenic liquid form have the same purity specifications as ALPHAGAZTM 1 and are useful when large volumes of gas are needed, such as nitrogen or argon used with ICP and FTIR instruments, or helium for cooling magnets in instruments such as NMR spectrometers.
