Abstract
A technological development is described through which the stable carbon-, oxygen-, and nonexchangeable hydrogen-isotopic ratios (delta C-13, delta O-18, delta H-2) are determined on a single carbohydrate (cellulose) sample with precision equivalent to conventional techniques (delta C-13 0.15 parts per thousand, delta O-18 0.30 parts per thousand, delta H-2 3.0 parts per thousand). 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.
