High purity Helium, Argon, Nitrogen, Oxygen, Hydrogen and Carbon dioxide for use across wide range of applications HELIOUS fills and supplies these gases in both cylinders, Packs and as cryogenic liquids according to the volumes and gas purities required by the customer. We supply a wide range of applications and industries including Oil and Gas, Petrochemicals, Food and Beverage, Metal Production, Environmental Monitoring and Protections, Research and High Technology Manufacturing. The Pure Gases we deliver are often supplied as part of a package of products alongside the wide range of offerings from our Specialty Gases portfolio.
Pure Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas or atomic gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super cooled to incredibly low temperatures are classified by their statistical behavior as either a Bose gas or a Fermi gas.
