Abstract: A system (102) for determining properties of a sample (114) comprises a LIBS detector (104,106) and an infra-red absorption detector (108,110) for interrogating a sample (114) to generate LIBS spectral data and infra-red absorption spectral data respectively; and a data processor (112) adapted to apply at least one chemometric prediction model, each constructed to link, preferably quantitatively link, features of both LIBS and absorption spectral data to a different specific property of the sample, to a combined dataset derived from at least portions of both the LIBS and the absorption data to generate therefrom a determination, preferably a quantitative determination, of the specific property linked by that model.

Abstract: A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS) may include obtaining granular organic material, forming a portion of the granular organic material into a sample pellet, and searing the organic material. The searing may include searing only an exposed end surface of the sample pellet on which LIBS analysis is to be performed. The method may include pressing the seared sample pellet to consolidate the material comprising the seared end surface.

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.
