Available ALPHAGAZ™Pure Gases

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.
