TY - JOUR A1 - Vogl, Jochen A1 - Pritzkow, Wolfgang T1 - Isotope reference materials for present and future isotope research T2 - Journal of analytical atomic spectrometry N2 - Isotope reference materials are essential to enable reliable and comparable isotope data. This article reviews the work in this field within the past years. The focus is on all stable elements, except for classical stable isotopes (H, C, N, O, S) and for radioactive elements. Currently available isotope reference materials are listed. The limitations of synthetic isotope mixtures being used to characterize these materials are discussed, as well as the limitations of the isotope reference materials, such as uncertainty and homogeneity. The needs for present research on isotope variations are being considered and are compared to the limitations of current isotope reference materials. This disagreement between both can only be solved by providing isotope reference materials defining a δ-scale for each element of interest. Such materials should be provided with additional data on isotope abundances whenever possible. As an outlook a possible outline for a new program on isotope reference materials is discussed.
