The activity generating the emissions is helium purification. The reference product is helium. Helium is an inorganic substance with a CAS no. : 007440-59-7. It is called helium under IUPAC naming and its molecular formula is: He. It is gas under normal conditions of temperature and pressure and it has no odor. The substance is modelled with >99.9% purity Modelling this substance in a solution requires the user to add the solvent of their choice in their models. On a consumer level, is used in the following products: Arts, crafts, and hobby materials, fuels and related products, metal products not covered elsewhere, non-TSCA use, magnetic resonance imaging equipment, toys, playground, and sporting equipment, leak detection gas, welding gas, diving, inerting gas, coolant, lifting gas for balloons. On industrial sites, the substance is used for the manufacture of products in the following sectors: Aeronautics, Process and Balloon gas, Welding, Medical Equipment, Diving gas, Functional fluids (closed systems), Functional fluids (open systems), Process regulators, leak detection gas, welding gas, lifting gas, inerting gas, coolant. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
