SA-spec- Oxygen

Reliable supply to meet your needs

Oxygen is essential to many industries. In the chemical industry, industrial grade oxygen is used to improve a large number of petrochemical processes. Oxygen is used in metal fabrication applications such as smelting, cutting and welding. Oxygen increases efficiency in a number of processes by reducing the amount of fuel used and decreasing carbon dioxide emissions.

In the healthcare industry, medical oxygen is used to treat respiratory insufficiencies, carbon monoxide poisoning and for resuscitation. In laboratories, ALPHAGAZ™ 1 oxygen provides 99.999% purity and is used as a bleaching agent, a combustible for flame detectors, an oxidizing agent and for silicon oxidation in semiconductor manufacturing. When your analytic and laboratory application is critical and requires ultra-high-purity oxygen, ALPHAGAZ 2’s 99.9995% pure oxygen is perfect. Both ALPHAGAZ grades of oxygen come in compressed gas cylinders equipped with open caps and SMARTOP™ valves.

Oxygen is available as a component in many gas mixtures. Oxygen in nitrogen gas mixtures are used as span gas calibration mixtures in engine emissions testing in the automotive industry. These gas mixtures are ISO 17025 accredited and Part 86 compliant. Oxygen gas mixtures are also used in environmental, industrial hygiene and safety and laboratory applications.




Oxygen gas mixtures are manufactured as Scott brand EPA protocol gases and are instrumental in helping you avoid non-compliance fines and downtime caused by inaccurate instrument calibration. Air Liquide’s specialty gas manufacturing facilities are registered participants of EPA’s Protocol Gas Verification Program (PGVP). Protocol standards are dual-analyzed, and for each reactive component, two separate analyses are performed and analyzed directly against metrology institute standards to determine their concentrations. Certificates of Accuracy are provided with each cylinder. 


Oxygen gas mixtures manufactured as CEM DAILY STANDARDS are used in applications where the use of EPA protocol gases are not required. Zero blend tolerance is available as a result of our proprietary ACCUBLEND™ technology. As a result, multiple cylinders exhibiting identical concentrations may be ordered, minimizing the need to recalibrate each time you change out a cylinder.
