In fifteen words or less, explain the significance of this contribution (Novel Aspect).: Particle isotope ratios via spICPMS can be applied to nuclear safeguard applications

Abstract Text:

Analysis of single particles has benefitted from advancements in spICP-MS, particularly through the use of various types of detectors. Quadrupole, time-of-flight, and multi-collector ICP-MS instruments have proven valuable across diverse fields, offering high throughput, high sensitivity, and accurate determination of isotope and element ratios within particle populations. A direct application of this technique is the characterization of particles from both known and unknown origins. One application of spICP-MS is its potential use for nuclear forensics and safeguards. Using spICP-MS, particles containing isotopes of interest can be rapidly screened, and their isotopic ratios determined, thereby supporting the development of particle screening techniques, quality control testing for particle reference materials, and detection of particles with unique elemental signatures.
