Propane

High-purity propane

Air Liquide manufactures propane pure gas with up to 99.9% purity. It is used in a variety of applications, including chemical synthesis, refrigeration and flame gas (AAS). Propane is also available as part of various Scott™ brand specialty gas mixtures, including two-component and multi-component gas mixtures used in multiple applications including industrial hygiene and safety, and laboratory.

Automotive

Scott brand propane gas mixtures are also used as span gas calibration mixtures in engine emissions testing in the automotive industry, and are ISO 17025 accredited and Part 86 compliant.  

Environmental

EPA Protocols: Propane 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 (COA) are provided with each cylinder.

CEM DAILY STANDARDS™: Propane 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 ACUBLEND™ technology. As a result, multiple cylinders exhibiting identical concentrations may be ordered, minimizing the need to recalibrate each time you change out a cylinder.

Oil and Gas

Propane is used in many hydrocarbon chromatographic standards, such as ASTM blends and hydrocarbon gas mixtures, as well as in natural gas and liquid standards, including calorimetric, high-ethane, extended analysis, GPA, helium and pipeline.

Related Supply Modes
