  • Induced breakdown spectroscopy detector system with controllable delay time
    Patent number: 6034768
    Abstract: The invention relates to high power, spark induced breakdown spectroscopy (SIBS) detectors with controllable delay time and to spark induced breakdown spectroscopy plasma generators with dual electrodes with specific electrode material, both for use in methods and apparatuses for detecting spectral signatures of atomic emissions, (e.g., from heavy metals such as lead, mercury, chromium, cadmium, arsenic, antimony and beryllium and radioactive materials such as uranium, plutonium, thorium and technetium) for measuring, for example, atomic concentrations of samples such as vapors and airborne particulates.
