Stable Isotope Analysis
Measuring δ¹³C, δ¹⁵N, δ¹⁸O, δ¹⁷O and δD
Understanding the composition and origin of various materials is essential across disciplines such as archaeology, environmental science, and hydrology. Stable isotope analysis offers a window into past climates, dietary habits, and water sources by examining the ratios of isotopes like carbon (δ¹³C), nitrogen (δ¹⁵N), oxygen (δ¹⁸O), and deuterium (δD). Accurate measurements of these isotopic signatures require precise analytical techniques to ensure reliable results.

Learn more about the applications of stable isotope analysis:
- Understanding δ¹³C and δ¹⁵N in Dietary Studies: Analyzing δ¹³C and δ¹⁵N values in human bone collagen is used to reconstruct dietary patterns in ancient populations. This data provides insights into the consumption of marine versus terrestrial resources, informing on ancient diet.
- The Role of δ¹⁸O in Paleoclimatology: By measuring δ¹³C and δ¹⁸O on carbonates such as coral, shell, and forams, researchers can apply results to past climate studies.
- Hydrological Applications of δD and δ¹⁸O: Analysis of δ¹⁸O and δD isotopes of water samples is employed to identify recharge sources and trace water sources and movement in environmental studies. The findings are used to aid in water resource management and conservation efforts.
