    摘要: 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.

    摘要: 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.

    摘要: 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.
