Raman LIBS

Raman/LIBS is an instrument that provides complete characterization of samples including elemental compositions as well as organic vs non-organic carbon and the molecular structure of the material.

LAUR: 16-22648

Benefits/Features

  • Comprehensive Analyses- LIBS/Raman provides comprehensive elemental and molecular analyses. The technical applications are rapid, requiring only several laser pulses.
  • Non-destructive Analysis- The LIBS/Raman analysis is non-destructive and results in only nanograms of material being removed. The analyses can be configured to be done in situ or at a distance.
  • Field Portable- The instrument can be used anywhere in the solar system.
