Laser-Induced Breakdown Spectroscopy (LIBS)
What is LIBS?
Laser-Induced Breakdown Spectroscopy is one of the newest methods for elemental analysis.
Often requiring a minimum of sample preparation, in LIBS a powerful pulsed laser ablates a sample. Particles from the ablation are analyzed in an analytical plasma formed by the focused laser pulse, often which is same pulse that performed the ablation. Elemental emission is collected directly, and either direct peak analysis or chemometric methods can be used for quantification.
LIBS can be used for depth profiling materials, elemental surface mapping, and bulk property analysis (using multivariate chemometrics). For example, LIBS technology can be used for heating value and ash content determination in coal.
