High Purity Gases

AGT International supplies a comprehensive range of hydrocarbon gases and liquids and associated special gases.

Our products are either purified from refinery-grade raw materials using a variety of techniques including molecular sieve and fractional distillation, or directly manufactured by hydrogenation and other techniques.

After manufacture, all products are certified in an on-site laboratory and supplied with a choice of certification – Composition, Batch or Individual analysis. Details of our full range of products are shown below.
