Deuterium is one of the three forms (called isotopes) of the first element, hydrogen. (get from standard definitions). The first hydrogen isotope is named ‘protium’ (the most abundant by far and the lightest), consisting of a proton and an electron. Protium is commonly expressed by the symbol ‘1H’. The second isotope is named ‘deuterium’ (much less abundant than protium but twice as heavy due to the addition of a neutron). Deuterium is commonly expressed by the symbol ‘D’ or ‘ 2H’. The third isotope is named ‘tritium’ (almost non-existent on Earth and three times as heavy as protium due to the addition of two neutrons). Tritium is a radioactive and luminous gas. The most important fact to know is that in nature, both protium and deuterium combine with oxygen to form water molecules.
Protium - 99.98% (by number) Deuterium - 0.0156% (by number) On our planet, for every 1,000,000 atoms of Hydrogen there are about 150 atoms of deuterium, (150 ppm).
Even though there is only 1 deuterium for every 6600 hydrogen in water, there is 4 times
more deuterium in human blood than the most important life giving elements and nutrients!
Our testing lab uses the Los Gatos research deuterium analyzer. This instrument uses
proprietary laser absorption technology called Off-Axis Integrated Cavity Output Spectroscopy *OAICOS+ that is highly effective and makes the analysis of a large number of samples possible with
great accuracy, efficiency and affordability.
