東日本イワタニガス List of Products and Services

"Deuterium (D2)" is an isotope of hydrogen and has different physical properties from hydrogen. We achieve stable supply without being constrained by the export restrictions of traditional exporting countries. Domestic production also enables short delivery times. Additionally, by establishing production technology utilizing hydrogen know-how, we have a production capacity that can respond to the era of high demand (annual production volume: 2,000 kL). [Features] - Stable "supply capacity" and "quality" - Production capacity that can respond to the era of high demand (annual production volume: 2,000 kL) - An isotope of hydrogen with different physical properties from hydrogen - Short delivery times achieved due to domestic manufacturing *For more details, please refer to the PDF document or feel free to contact us.

Iwata's Helium Network Iwata conducts a consistent operation from import to sales in-house. With the largest number of imported containers in Japan (owned by the company) and two helium centers nationwide, we have established a robust system for stable supply and emergency shipments as Japan's top helium supplier. We provide a one-stop service that includes site visits for delivery to each user, proposals for supply quantities and delivery dates, and coordination with various system users. Additionally, to ensure safe and secure operations, two certified filling personnel, who have cleared strict certification criteria, visit each field as a team.

**Deuterium Oxide (Heavy Water)** It is used as a moderator in nuclear power generation. It is a compound of deuterium and oxygen, and due to its property of being less likely to absorb neutrons compared to light water, it improves fuel efficiency. Additionally, it is used as a heavy solvent in NMR, as well as a raw material and tracer in pharmaceuticals. **Deuterium** Deuterium (D2) is an isotope of hydrogen and has different physical properties compared to regular hydrogen. Due to its characteristics, its applications have increased in recent years, being used in semiconductor longevity, cancer treatment, and testing. Recently, research on nuclear fusion has been actively conducted, and the demand for deuterium has further increased due to its use in DT and DD reactions as nuclear fusion reactions. The Iwatani Group, as a manufacturer, ensures stable supply of deuterium gas without being constrained by export restrictions from traditional exporting countries. Domestic production also enables short delivery times. *For more details, please refer to the PDF document or feel free to contact us.*

Heavy water (D2O) is a molecule in which the isotope deuterium (D) atom is bonded to an oxygen (O) atom instead of a hydrogen (H) atom. Deuterium contains a neutron that hydrogen does not have, resulting in an increased mass and different physical properties. Heavy water is used as a raw material in pharmaceuticals and as a tracer. Deuterium can be incorporated into drug molecules as a substitute for hydrogen, improving the stability and duration of the drug's effects. Additionally, it is used as a moderator in nuclear power generation. When neutrons collide with deuterium, they lose energy more than when they collide with hydrogen, making nuclear fission reactions more likely. Therefore, heavy water is an essential substance for enhancing the efficiency of nuclear reactors. It is also used as a heavy solvent for NMR. [Features] - Deuterium (D) atoms, an isotope, bond with oxygen atoms instead of hydrogen (H) atoms. - Deuterium contains a neutron that hydrogen does not have. - Increased mass results in different physical properties. *For more details, please refer to the PDF document or feel free to contact us.
