Abstract
A technological development is described through which the stable carbon-, oxygen-, and nonexchangeable hydrogen-isotopic ratios (δ13C,
δ18O, δ2 H) are determined on a single carbohydrate (cellulose) sample with
precision equivalent to conventional techniques (δ13C 0.15‰, δ18O 0.30‰,
δ2 H 3.0‰). This triple-isotope approach offers significant new research
opportunities, most notably in physiology and medicine, isotope biogeochemistry,
forensic science, and palaeoclimatology, when isotopic analysis of a common sample is desirable or when sample material is limited.
