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, and particles from the ablation are analyzed in an analytical plasma formed by the focused laser pulse, often the 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, or even bulk property analysis (using multivariate chemometrics). An example of the latter includes heating value and ash content determination in coal, for example. Call us if you have LIBS questions - we've been working with LIBS since 1998!
