Abstract
Methods for laser induced ablation spectroscopy (LIBS) are disclosed. Light from laser ablation can be gathered into a lightguide fiber bundle that is subdivided into branches. One branch can convey a first portion of the light to a broadband spectrometer operable to analyze a relatively wide spectral segment, and a different branch can convey a second portion of the light to a high dispersion spectrometer operable to measure minor concentrations and/or trace elements. Emissions can be analyzed using a plurality of spectrometers having distinct and/or complementary capabilities, and with a synergistic method using inductively coupled plasma mass spectrometry.
