Silver Isotope Materials
Most natural samples exhibit only very small deviations from the reference material NIST SRM 978a. Using multi-collector ICP-MS, a δ109Ag measurement uncertainty of 0.05 ‰ or better can be achieved. This allows detecting commercial products fortified with silver by identifying variations
