Choosing the right pure specialty gas for a particular instrument and application can be confusing. Air Liquide simplifies gas selection by reducing a complex variety of available gas grades down to two levels of purity as represented in our ALPHAGAZ product line. ALPHAGAZ 1, with guaranteed low impurity levels, is recommended for most laboratory, analytic and process control applications. ALPHAGAZ 2 offers higher purity levels that are well suited for demanding applications that need ultra-high purity. We also offer a cryogenic pure gas solution for nitrogen, argon and helium. ALPHAGAZ pure gases are typically supplied in compressed gas cylinders with our innovative SMARTOP™ valve that simplifies gas handling and improves safety.
