Carbon Monoxide

High-purity carbon monoxide

Air Liquide manufactures carbon monoxide pure gas with minimum purity up to 99.97%. It is used in a variety of applications, such as catalyst regeneration, chemical synthesis and atmosphere reduction. Carbon monoxide as a pure specialty gas is also available in nonreturnable Mini-MixTM Transportable cylinders when smaller quantities of gas are needed for laboratory applications.

Carbon monoxide is available as a component in many gas mixtures, including two-component, three-component and multi-component gas mixtures. Carbon monoxide is used in nitrogen mixtures to form span gas calibration mixtures in engine emissions testing in the automotive industry. It is both ISO 17025 accredited and Part 86 compliant. Carbon monoxide gas mixtures are also used in environmental, industrial hygiene and safety, and laboratory applications.

EPA PROTOCOLS

Carbon monoxide 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. In addition, carbon monoxide is also offered as part of multi-component EPA protocols to meet any specification.

CEM DAILY STANDARDSTM

Carbon monoxide 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. These mixtures are available in two-component and multi-component variation.
