Technical Guide: IRMS Reference Materials

We are often asked by customers about our reference materials for IRMS. To help explain these points we have prepared a technical guide on these materials.

All IRMS data should be traceable to Primary reference standards. These primary references are materials that have been selected and assigned definitive delta (δ) values for the light elements H, C, O, N and S and are isotope ratio scale defining.

Additional Information available: IRMS Refs Tech Bulletin - June 2017.pdf
