Instrument grade gases from Afrox are quality-guaranteed, purpose-designed products for use in laboratories. Sub-Saharan Africa’s largest gases company has invested millions of Rands to ensure these products are cutting-edge. In pursuit of this, Afrox is currently commissioning a new state-of-the-art filling and testing facility and is poised to launch the long-awaited HiQ grades of speciality gases.

The Afrox range includes carrier gases such as helium, nitrogen, argon and hydrogen, with minimum purity of 99,999%, or N5.0. These are analysed and certificated in a high-tech laboratory by experts. The instruments used range from zirconia cell technology that can detect oxygen at parts per billion levels, to gas chromatographs with pulse discharge helium ionisation technology, very sensitive to impurity detection on pure gases.

Gas calibration standards are made gravimetrically (by mass), which is more accurate than barometric (pressure) measurements. At the new facility, mixtures can now be combined to higher accuracy using the latest mass comparator technology.

This state-of-the-art facility has been designed with the environment in mind and all gases released during the process will be captured by a world-class scrubber system. The scrubber plant was designed with a very high safety factor to prevent any release of untreated gas into the atmosphere.

Afrox is also in a commanding position to freely obtain EPA protocol mixtures from an associate company. 

All the improvements and additional capacity is aimed at improving customer service levels and quality while keeping up with the growing demands of this fast-moving market.
