LIBS- Laser Induced Breakdown Spectroscopy

The LIBS2500plus Laser-induced Breakdown Spectrometer Measurement Systems are detection systems that permit real-time qualitative measurements of elements in solids, solutions and gases. These broadband, high-resolution systems provide spectral analysis across a wide 200-980 nm range (depending on the system) at a resolution of ~0.1 nm (FWHM).

Applications of LIBS2500 PLUS

The LIBS technique is useful for a variety of applications:

  • Environmental monitoring (soil contamination, particulates)
  • Materials analysis (metals, plastics)
  • Forensics and biomedical studies (teeth, bones)
  • Military and safety needs (explosive particles, chemical and biological warfare agents
  • Art restoration/conservation (pigments, precious/ancient metals)
