Technical report reports expansion of international isotopic reference materials across chemical elements, highlighting standard gaps in heavier elements.

Key Points

To review the historical development, current availability, and remaining gaps in international reference materials and delta scales for stable isotope-ratio analysis.
Evaluated the historical expansion and inventory of international measurement standards and secondary reference materials since the 1950s.
Assessed element coverage and standard calibration requirements across natural and technical sample measurements.
Primary measurement standards expanded from 3 to more than 30 across >25 elements, supported by over 150 distributed secondary reference materials primarily covering H, Li, B, C, N, O, and S.
Primary measurement standards remain absent for several elements, including magnesium, iron, tellurium, antimony, molybdenum, and germanium.
Authors must publish the delta values of secondary reference materials used to ensure transparency and traceability to primary isotope scales.
