The “purity” of an organic compound typically refers, in practice, to an assignment of the mass fraction content of the primary organic component present in the material. The “purity” value of an organic primary calibrator material is the ult

Rationale In recent years, the primary reference material (RM) for the VPDB scale, NBS19, has become unavailable, and the RM used for low-end scale-anchoring, LSVEC, was found unsuitable due a drift in the δ13 C value. Given these problems, new RMs

RATIONALE LSVEC, the second anchor Reference Material (RM) for the VPDB δ13 C scale realisation, was introduced in 2006. In 2015, its δ13 C value was found to be drifting and, in 2017, its use as an RM for δ13 C was officially discontinued by IUPA

The stable isotope scales of the light elements (H, C, O, S) are artefact-based (related to a primary reference material) and their practical realisation is based on several refence materials (RMs) traceable to the primary RM on a respective delta-sc

Stable isotopes are widely used with applications in forensics, ecology, biogeochemistry, atmospheric sciences, and hydrology. Isotope data are frequently compared and combined, which requires data of high quality. This brings to the attention how co
