Abstract
An object of the present invention is to provide a carbon stable isotope enrichment method that does not require safety measures against combustibility and toxicity and that enables high-concentration 13C enrichment without isotope scrambling, and the present invention provides a carbon stable isotope enrichment method including a distillation step for enriching carbon tetrafluoride stable isotope molecules containing 13C by distilling raw material carbon tetrafluoride containing multiple types of carbon tetrafluoride stable isotope molecules in a distillation column group in which multiple distillation columns are cascaded.
Claims1
A carbon stable isotope enrichment method including a distillation step of distilling raw material carbon tetrafluoride containing multiple types of carbon tetrafluoride containing a stable isotope in a distillation column group in which multiple distillation columns are cascaded, and enriching carbon tetrafluoride containing a stable isotope 13C.
