General description

Water-18O is an isotopic analogue of water.

Application

Water-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).

Packaging

Packaged in septum-sealed serum bottles.
This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.
