Centrifugal Separation of Carbon Isotopes Using Heptafluoropropane as Processing Gas

Journal of Isotopes, 2020
The demand for stable isotopes has increased in the field of medical diagnosis, biopharming, quantum communication and so on. Natural carbon has two stable isotopes: 12C (98.89%) and 13C (1.11%). 13C in high abundance is mainly used in tracer field.
