Abstract
Apparatus for laser induced ablation spectroscopy (LIBS) is disclosed. An apparatus can have a computer, a pulsed laser and a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a first optical spectrometer and a different branch can convey a second portion of the light to another optical spectrometer. The first spectrometer can be relatively wideband to analyze a relative wide spectral segment and the other spectrometer can be high dispersion to measure minor concentrations. The apparatus can have a plurality of spectrometers with distinct and/or complementary capabilities, and can include an inductively coupled plasma mass spectrometer and data and instructions in tangible media operable to obtain a synergistic composition analysis based on optical spectra and ion mass to charge ratio peaks from the mass spectrometer.
