Applications of LIBS

  1. 1. Industrial Applications of LIBS Seminar by Deepak Rajput PHYS 605 Advanced Topics: Laser Spectroscopy July 10, 2007 Center for Laser Applications University of Tennessee Space Institute Tullahoma, TN 37388 Email: drajput@utsi.edu Web: http://drajput.com 1
  2. 2. Applications Metals and Alloys Processing Scrap Material Sorting and Recycling Nuclear Power Generation and Spent Fuel Reprocessing 2
  3. 3. Metals and Alloys Processing Slag Analysis Steel making Liquid Steel Analysis Identification of Pipe Fittings 3
  4. 4. …../ Slag Analysis Thumb Rule: “The quality of steel is determined by the quality of slag !!” Reduces analysis time by ~40% Superseded: XRF Spectroscopy 4
  5. 5. Page 405, Laser Induced Breakdown Spectroscopy: Fundamentals & Applications, Cambridge University Press, 2006 5
  6. 6. …../ Liquid Steel Analysis Goal: To receive a fast elemental analysis of the steel composition. (e.g., HSLA steel, Stainless Steel, etc.) Reduces analysis time by ~50% Superseded: Spark OES 6
  7. 7. …../ Identification of pipe fittings Corrosion: The biggest problem in oil and gas companies. Variety of steel grades are used in these companies Mismatch in pipes can lead to corrosion with severe consequential damage Laser Identification of Fitting and Tubes (LIFT) is used. Superseded: Spark OES 7
  8. 8. Scrap Material Sorting and Recycling Segregation of brominated plastics from non-brominated plastics Sorting of metal alloys by grade type or group Sorting of technical glasses according to their chemical composition 8
  9. 9. Strengths of LIBS Rapid Accurate Reliable 9
  10. 10. Thank You “The great pleasure in life is doing what people say you cannot do” 10
