LIBS is particularly useful for depth analysis, as the laser can be re-focused on the same location of a sample surface and provide depth profiling at a resolution of 100’s of nanometers per pass, depending on the sample matrix. In addition, a range of laser spot sizes is available (~20-200 µm), and a sub-micron resolution motorized sample stage allows for the laser to scan over a sample surface, providing spatially resolvable elemental maps, allowing for multivariate statistical analysis. LIBS can detect any naturally occurring element down to down to parts-per-million levels, depending on the sample matrix.
