Laser Induced Breakdown Spectroscopy (LIBS) - LIBS.ID,

SPE ls raman.ID + LIBS.ID

Results

Aluminium particle LIBS spectra Aluminium particle LIBS spectra:
83µm particle, elongation 2.1, LIBS Result: Al, Cu, Si
Database build and differentiation of 4 different type of Glass depending on their content of Na, K and Ca and other minor variations.

Advantages

  • particle size range from 5 µm up to 5 mm with morphologically directed spectroscopy
  • very fast emission spectroscopy (1s/Particle) – ambient air conditions
  • delivers element information from Hydrogen up to Uranium
  • identification of metals, minerals and inorganic particles
  • quantification of the elements contents to a 0.001-1% accuracy
  • material ablation depth information allows micro-drilling into the material
  • immediate combination with Raman and image analysis makes it perfect for unknown material characterization

 

 

How it works

Laser Induced Breakdown Spectroscopy, LIBS is an element specific emission spectroscopy. Emission is induced by a laser pulse interacting with the particles material and forming a plasma. Energy levels of the emitted light is correlated to the chemical element present in the plasma.
