Every ablation event generates a spectrum. Scanning of the laser beam with respect to the sample or vise vera and through spectral assignment to space and depth coordinates, we can create 2D and 3D maps of the elemental (or isotopic) composition of any sample. We couple these laser sampling technologies with optical emission and mass spectrometry technologies (for more information click here).
These laser ablation-based spectroscopy technologies are much more sensitive than the majority of traditional spatially and depth-resolved analysis technologies (i.e. chemical imaging). Limits of detection range from parts per million to parts per billion, or better. Further, two chemical imaging technologies, such as LIBS/LAMIS and LA-ICP-MS can be combined to create elemental or isotopic maps, from the same ablation sampling event. These are complementary techniques and the combination of the two can provide broad chemical information and help overcome limitations of each technology due to interferences.
