Heavy metals migrate throughout the ecosystem with water cycling, posing a significant
threat to food safety, environmental safety, and human health. Atomic spectrometry has …

As evidence for tracing the history of nuclear materials, in situ detection of neodymium
isotopes using tunable diode laser absorption spectroscopy (TDLAS) was investigated. A …

This study introduces a novel optical system integrating laser ablation with saturated
absorption spectroscopy (LA-SAS) for the detection of neodymium isotopes, crucial for the …

Uranium was measured by laser induced breakdown spectroscopy (LIBS) with a limit of
detection of 1.3 picograms with spectral-peak height as the analytical parameter, which …

Rubidium isotope analysis and isotope ratio determination are significant in the fields of
environmental monitoring and geological dating. A measurement system for rubidium …

We have applied cavity ring-down spectroscopy (CRDS) to the study of the 166Er isotope in
an atomic beam. These measurements were realized with an external cavity diode laser …

Portable, easy to use isotope identification instruments are required for preliminary
investigations of nuclear post-detonation events. Having preliminary data allows for proper …

The design and demonstration of an optical analysis system based on wavelength
