About our research...Advanced methods employed for the isotopic charaterization of materials include time-of-flight secondary ion mass spectrometry (ToF-SIMS), conventional SIMS, accelerator mass spectrometry (AMS), isotope ratio mass spectrometry (IRMS), and low-level counting (LLC) by highly-discriminated detection of natural radioactivity. Nuclear measurement techniques can measure differences between chemically-identical materials, help to discriminate sources of materials, and be used in isotope dilution methods to definitively characterize SRMs for elemental and chemical abundances |
