Abstract: A Laser Induced Breakdown Spectrocopy (LIBS) system (2) for the analysis of a sample pellet (12) of a consolidated granular material retained in a tubular container (20), the system (2) comprising a laser source (4) configured to emit a pulsed laser beam (6) towards an exposed surface of the sample pellet (12); and a sample station (18) configured to hold the tubular container (20) with the sample pellet (12) orientated to present the exposed surface towards the pulsed laser beam and comprising an actuator configured to slide the sample pellet (12) along a movement axis out of the tubular container (20) and thereby present a portion of an outer surface (10) of the sample pellet (12) previously constrained by an inner surface of the tubular container (20) as the exposed surface.
