Pure Gases

Ultra Pure Gases

From A - X (Acetylene to Xenon) we are able to supply you with an extensive range of pure gases along with the correct specification of Speciality Gas control equipment to ensure that the purity you require is maintained accurately through to your point of use.

More than 100 pure gases throughout their range of purities are available to match your specific requirements and applications. Just contact our Speciality Gas help desk advisor and discuss what you need from us.

Electronic gas purities are available to you up to 99.9999% (6.0) purity from within our LI-PUR product and service programme.
These are precision manufactured products designed to exceed the stringent requirements of the microelectronics and fibre optic industries.

Only proven materials are used including hardened and tempered steel with internal surface treatment, passivated aluminium alloy or electropolished stainless steel cylinders. Only the use of stainless steel valves will do for the elimination of low particle generation, to promote leak tight integrity, superior handling, purge functionality and reliability. Valve options available include flow restrictors, pneumatic operation and metallic seal connections.

Preparation of these cylinders is essential and includes intensive treatment using turbomolecular pumps, particle emission and residual contamination analysis prior to filling.

Cylinder inventory and filling systems are maintained with strict segregation to avoid the risk of cross contamination. Sophisticated filling systems and procedures combine with filtration and purification techniques to preserve the purity and accuracy of the final product.

Special sampling techniques primarily for corrosive gases and trace metals along with leading edge methods of analysis including gas chromatography, (FT-) infra-red absorption, atomic absorption and ICP mass spectrometry and particle counting, verify that the quality of our products is assured.
