Abstract: A Laser Induced Breakdown Spectrocopy (LIBS) system for the analysis of a sample pellet of a consolidated granular material retained in a tubular container may include a laser source configured to emit a pulsed laser beam towards an exposed surface of the sample pellet; and a sample station configured to hold the cylindrical tubular container in one or more orientations to present an exposed surface of the sample pellet towards the pulsed laser beam. The sample station may induce linear movement of the sample pellet along an axis and to expose a portion of the outer side surface of the sample pellet previously constrained through contact with an inner surface of the cylindrical tubular container. The sample station may induce rotational motion of the outer side surface of the sample pellet around the movement axis to present the portion of the outer side surface as the exposed surface.

Abstract: An optical spectrometer (102) comprises an adjustable sampling space (104) having two generally opposing, relatively movable, side-walls (106,108) which are here substantially formed of optically translucent material and between which in use a sample for analysis is charged and an actuator (116) mechanically coupled, here via a worm drive (118), to one or both of the opposing side-walls (108) and operable in response to a command signal applied thereto to effect their relative movement. The spectrometer (102) further comprises an optical position sensor (110,112,114) adapted to detect interference fringes generated by optical energy traversing the distance between the side-walls (106,108) a plurality of times and to generate the command signal in dependence thereof and preferably also adapted to generate an output indexing intensity against an indication of wavelength usable in the spectrometric analysis of a sample material within the sampling space (104).
