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.Â
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. Â
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 gases see our Certified Reference Materials or Calibration Gas pages.

Lecture bottles have a 0.4 litres water capacity, measure 310 mm long by 50 mm diameter and come with a CGA 180 valve. Lecture bottle stands are also available.
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.
