ELECTRONICS GASES

Argon is considered a rare atmospheric gas which is colourless, odourless, tasteless and nontoxic. It is considered extremely inert and forms no known chemical compounds.

Argon is slightly soluble in water. The concentration of Argon in the atmosphere by volume is 0.93%.
Argon is principally shipped and used in gaseous form for neon signs, lasers, incandescent and fluorescent lamps, electronic tubes, window insulation, welding, and semiconductor applications.

Helium is a rare atmospheric gas which is colourless, odourless, tasteless, nontoxic, non-flammable and only slightly soluble in water. The concentration of Helium in the atmosphere by volume percent is 5.24 x 10-4.

Helium is principally shipped and used in either gaseous or liquid form for nuclear reactors, semiconductors, lasers, light bulbs, superconductivity, instrumentation, medical applications, cryogenics, MRI and R & D laboratory research.
