  • Method of laser-induced breakdown spectroscopy in air
    Patent number: 9891173
    Abstract: A method for detecting an element in a sample using molecular emission by double pulse laser-induced breakdown spectroscopy is provided. The method includes observing emissions from molecules including the element to be detected. The method is particularly useful for detecting halogens, whose elemental emissions are difficult to detect, rare earth elements and boron.
    Type: Grant
    Filed: May 29, 2014
    Date of Patent: February 13, 2018
    Assignee: LASER DISTANCE SPECTROMETRY LTD.
    Inventors: Michael Gaft, Lev Nagli
  • Method and apparatus for quantitative analysis of samples by induced plasma (LIP)
    Patent number: 9476829
    Abstract: A system for classifying moving materials in real time, the system including a laser pulse generator operative to generate at least first and second laser pulses which impinge on the same impingement location on the moving materials, the first and second laser pulses being separated in time by up to 10 microseconds; and an absorption detector operative to sense an absorption spectrum at the impingement location over a detection time duration of up to 20 nanoseconds following the second laser pulse.
