Isotope Ratio Mass Spectrometry
Isotope Ratio Mass Spectrometry (IRMS) is an analytical technique that measures the relative abundance of stable isotopes (H, C, N, O, S) and some radiogenic isotopes (e.g., ⁸⁷Sr/⁸⁶Sr) in samples with high precision. Standardized by Coplen and colleagues, IRMS enables paleoclimate reconstruction, source tracing (diet, water origin), geochemical fingerprinting, and age dating through radiogenic isotopes.
