  • Patent number: 9383260
    Abstract: Systems, methods, compositions, and apparatus for laser induced ablation spectroscopy are disclosed. A sample site position sensor, stage position motors operable to move the stage in three independent spatial coordinate directions, and a stage position control circuit can move an analysis sample site to selected coordinate positions for laser ablation. Light emitted from a plasma plume produced with 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 from a plasma plume can be simultaneously analyzed in various ways using a plurality of spectrometers having distinct and/or complementary capabilities.
