本文介绍了一种在单一碳水化合物（纤维素）样品上测定稳定碳、氧和非交换氢同位素比值（δ（13）C，δ（18）O，δ（2）H）的技术进展，其精度相当于常规技术（δ（13）C 0.15‰，δ（18）O 0.30‰，δ（2）H 3.0‰）。这种三同位素方法提供了重要的新的研究机会，特别是在生理学和医学，同位素地球化学，法医学和古气候学，当一个共同的样品的同位素分析是可取的，或当样品材料有限。
A technological development is described through which the stable carbon-, oxygen-, and nonexchangeable hydrogen-isotopic ratios (δ(13)C, δ(18)O, δ(2)H) are determined on a single carbohydrate (cellulose) sample with precision equivalent to conventional techniques (δ(13)C 0.15‰, δ(18)O 0.30‰, δ(2)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.
