Stable isotope	Heavy oxygen water is also called water-18O, an isotope of water. Natural abundance of hydrogen and O -100 compounds. Some physical properties are slightly different from ordinary water. The vapor pressure ratio of the liquid phase is. It is prepared by water distillation, NO low-temperature distillation and oxygen low-temperature distillation. Mainly used in chemistry, biology, medicine, agriculture, geology and other scientific research fields as tracers. Manual calibration samples can also be prepared with isotopic pure H216O.
traits	colorless, odorless and tasteless liquid.
use	heavy oxygen water is water-18O, 97 atom O is used for DNA stable isotope detection (SIP) to study the growth and death of microorganisms in environmental samples. Used as tracers in scientific research fields such as chemistry, biology, agriculture, and geology.
Preparation	Currently, heavy oxygen water is mainly prepared by redox reaction of H2 and O2 under the action of precious metal catalysts. Among them, O2 is produced by electrolysis of double standard water (D2O), and D2O is obtained by distillation of natural water.
