D2O for Pharmaceutical


Hospital diagnostics labs and university laboratories all use deuterated compounds in their medical research, including cancer research.

D2O for Diagnostics


Deuterium as a tracer, is applied in environmental studies, water and waste-water mapping, and more recently in the monitoring of hydraulic fracturing.

D2O for Hydrology

Fibre Optics

Deuterium extends the life of fibre-optic cables by reducing the chemical reaction rate which leads to deterioration of the light transmission.
