What is PurityPlus?

PurityPlus® producers are a group of Independently Owned Specialty Gas producers in North America working through the Independent Welding Distributors Cooperative. A fundamental part of the PurityPlus® program is its consistent Standard Operating and Quality Assurance Procedures that all producers must meet.

Integral to the program is a sequence of levels or tiers that define the proficiencies of each partner. These tiers represent the process and analytical capabilities required to supply gases of defined purities, aligning with generally accepted impurity maximums and analytical tolerances.

For example, all certified PurityPlus® producers can package and certify Nitrogen and Argon to grade 5.0 (Ultra High Purity.) Moving up in the tiers usually involves additional analytical and gas-filling equipment to fill higher purity atmospheric gases. Calibration and verification are executed through NIST-traceable standards, most typically SRM’s, and verified by annual round-robin testing.
