Abstract:

LIBS (Laser Induced Breakdown Spectroscopy) is ideal for analyzing light elements, for example Li, Be, S, C, O, N, H and the halogens; elements that are difficult or impossible with the Inductively Coupled Plasma Mass Spectrometer (ICP-MS). In addition, LIBS is good for major concentrations which again are problematic in the ICP-MS, expanding the dynamic range of analysis. These two detection modalities complement each other. LAMIS (Laser Ablation Molecular Isotopic Spectroscopy) measures isotopes in laser plasmas at atmospheric pressure from molecular emission band spectra in addition to atomic and ionic line spectra. We developed LAMIS for measuring B, C, H, D, Sr and other isotopes. The talk will describe the simulatenous measurement of photons (LIBS, LAMIS) with particles (ICP-MS) for detecting of every element/isotope in a sample with a single laser pulse, and the use of LIBS for measuring uranium isotope ratios at atmospheric pressure with picogram limits of detection.
