Carbon-13 (C-13) – Stable Isotope

C-13 is a non-radioactive, stable isotope of carbon widely used in medical diagnostics, metabolic research, and environmental science. Its unique properties enable precise tracking of biochemical and geochemical processes.

Applications:

• Stable isotope-labeled compounds for metabolic and nutritional studies

• Breath tests for detecting H. pylori and liver function diagnostics

• Environmental tracing in carbon cycling and climate research

• NMR spectroscopy and structural analysis

• Industrial process tracing and quality control

Carbon isotopes and mainly C-13 is used extensively in many different applications. C-13 is used for instance in organic chemistry research, studies into molecular structures, metabolism, food labeling, air pollution and climate change. C-13 is also used in breath tests to determine the presence of the helicobacter pylori bacteria which causes stomach ulcer. C-13 can also be used for the production of the radioisotope N-13 which is a PET isotope. The C-12 atom has been given the atomic weight of exactly 12.000000000 and is used as the basis upon which the atomic weight of other isotopes is determined.
