Heavy-oxygen water Usage And Synthesis
Chemical PropertiesColourless Liquid
UsesWater-18O, 97 atom % 18O is used in DNA stable isotope probing (SIP) to investigate microbial growth and death in environmental samples.
UsesWater-18O is an isotopically modified water, which is appropriate for PET applications.It can also be used:
  • In paleoclimatology, hydrology, and plant ecology to determine soil stable oxygen isotope analysis of plant cellulose using δ18O.
  • To determine the diffusion of moisture into crystals using secondary ion mass spectrometry (SIMS).
DefinitionChEBI: A form of water consisting of two hydrogen atoms covalently bonded to an oxygen-18 atom.
