Abstract
Methods for laser induced ablation spectroscopy are disclosed. A position sensor, and position motors can move a sample stage in three independent spatial coordinate directions, and a stage position control circuit can move an analysis sample site to selected coordinate positions for ablation. 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 simultaneously analyzed in various ways using a plurality of spectrometers having distinct and/or complementary capabilities, and isotope analysis of a sample can be performed.
