High Pressure Cylinders

Gas Mixtures in High Pressure Cylinders

CAC GAS provides specialty gas mixtures in high pressure gas cylinders for all applications including gas chromatography, process gas analysis, environmental monitoring or gas detection. Made gravimetrically all mixtures have international traceability via the U.K. National Physical Laboratory or UKAS standards.

ISO 17025 mixtures for the hydrocarbon industry including LNG gas standards, refinery gases and sulphur gas standards are available. We produce simple binary mixtures through to complex multi-component gas mixtures in a range of cylinders sizes.

All valve types are available including AS, BS, CGA and DIN as required. Gases are supplied with a certificate of composition. Cylinders are labelled with the gas volume, pressure, our reference, date of manufacture and shelf life.

Specialty Gases are also available in disposable/non-refillable cylinders in a variety of sizes.

For more information on our 3 classifications of gas mixtures (Traceable, Certified, Accredited) visit our Specialty Gas Mixtures page.

The ISO 17025 Marine Emissions test kit provides SO2/CO2 calibration gases for marine stack gas analysis. The kit provides the equipment necessary to calibrate and test CEMS (Continuous Emissions Monitoring Systems) to meet airborne pollution levels in the MARPOL Annex VI. The kit comes with the mobile carrying case; two 3L (600 litres of gas @ 200bar) high pressure cylinders of chosen gas; a compact, single-stage cylinder pressure regulator and tubing.

The case is made of highly impact-resistant plastic. It's temperature resistance is between -40 ° C and +80 ° C. The all-round impact protection features make it shock and impact absorbing. This case is lockable with an ergonomic, telescopic handle and wheels for a secure and convenient solution.

Gas Capacity: Water Volume 3 Litres

The 150A aluminium cylinder is designed for corrosive gas mixtures of all types including CL2, H2S, NH3, SO2 and many others. Each cylinder comes with a CGA valve and comes with an NIST traceable certificate.

The 150w “white top” cylinder is a specially conditioned cylinder providing long term stability for specific corrosive gas mixtures. Used for all Nitrogen dioxide mixtures and EPA Protocol gas mixtures, the white top cylinder provides a 36 month stability period.
