Mass spectrometry, in particular ICP-MS, is a powerful technique to measure elemental isotopes. The measurement of individual isotopes can reveal important information about the origin of the element in the sample. Isotope Dilution Mass Spectrometry (IDMS) is often touted as being the most accurate mode of sample ‘unknown’ analysis.
VHG offers a selection of isotope reference materials. These are non-radioactive, "stable" isotopes and can be handled like any aqueous metal standard. Each standard comes with a Certificate of Analysis (COA) that documents the certified isotopic abundances.
