Coregas do laboratory gases too

---

Regular readers of Australian Hospital and Health Bulletin probably recognise Coregas as a medical gases supplier, but they do more than just that. In fact, they have been supplying Australian laboratories with their range of high purity gases and gas mixtures for over 41 years.

As a gases specialist, coregas manufactures and supplies a range of medical, specialty and industrial gases throughout Australia, but their laboratory gases range is one of their core competencies. Available in a range of sizes from individual cylinders up to custom-built complete laboratory supply systems and cryogenic storage systems, Coregas specialises in ensuring laboratories can access the correct gases in the volumes and frequencies they require, no matter the application.
From high purity common gases such as helium, argon and nitrogen to the rarest of gases such as xenon and krypton, plus specially made multiple component gas mixtures suitable for testing and calibration uses, they work to the precise standards laboratories need for their gases, especially in the hospital environment
“We know the importance of high purity, reliability and traceability of laboratory gases, so we’ve organised our production, delivery and quality control system around maximising all three,” says Victor Chim, who heads up Coregas’ specialty gases team.
Ultra high purity gases
Many Coregas gases are available in a range of purities, but the laboratory gases range is available in purities of up to 7.0 (99.99999%), including common gases such as nitrogen, oxygen, argon, hydrogen, helium, carbon dioxide, instrument air and instrument acetylene. Their methodical approach includes carefully preparing cylinders and selecting valve materials that are compatible with the contents.
Other gases
Too large to list here, the Coregas range also includes

• Electronic gases, eg silanes, ammonia, nitrogen trifluoride, chorines and halocarbons


• Rare gases, eg neon, krypton and xenon


• Isotopes etc He-3 and Xe-129


• Liquefied gases for labs that need bulk quantities ranging in size from 35-240 litre flasks to custom bulk installations.


• Calibration gases, from simple inert gas mixtures to the most difficult to produce moisture test gases (low parts per million H2O in CH4 or H2O in N2). Their range of reactive gas mixtures include CO, NO, NO2, SO2, NH3, H2S and Mercaptans in low parts per million or percentage levels.

Reliability
Operating one of the largest production and storage facilities in the southern hemisphere and an Australia-wide distribution network, Coregas provides a reliable supply of high quality gases under short lead times, whether locally produced in bulk or other gases sourced through their global supply chain.
Stability and accuracy
Coregas ensure stability and accuracy of their calibration gas mixtures by using:

• Only ultra-high purity gases


• Advanced thermodynamic techniques to calculate gas composition


• Gravimetric filling techniques, which produce more accurate calibration gas standards than volumetric methods because gas concentrations are not affected by temperature changes inside the cylinder during gas compression.


• Chemical testing for stability to ensure they meet the strictest requirements.

Accreditations and traceability
To prove the standards of excellence of their products, Coregas maintains 3 key accreditations

• ISO 9001: quality management accreditation for the manufacture of standard gas mixtures (batch certified): traceable to their in-house calibration gas standards, relative uncertainty = ±2%.


• ISO/IEC 17025: NATA certified accreditation for the manufacture and testing of calibration gases (individually certified and prepared gravimetrically): traceable to internationally approved standards which offer a relative uncertainty of approximately ±1%


• ISO Guide 34: accreditation for the manufacture of reference material to ISO6142: the highest accredited level for gravimetrically-prepared calibration gas mixtures, traceable to National standards according to the International System of Units (SI). It offers a relative uncertainty of approximately ±0.5%.

Equipment
Coregas equipment range runs from laboratory grade gas regulators through to complete laboratory gas distribution systems and cryogenic storage systems.
