    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 non-intrusive method for determining an indication of wholesomeness of an unopened item of packaged aliment comprising the steps of illuminating an unopened item of packaged aliment with electromagnetic energy at a plurality of different wavelengths through a suitably transparent region of the packaging so as to interact with the packaged aliment; obtaining spectral information regarding the interaction of the plurality of different wavelengths with the packaged aliment as subsequent spectral information; interrogating the packaging to access original spectral information regarding a previous interaction of the plurality of wavelengths with the same unopened item of packaged aliment and associated with the packaging; comparing some or all of the subsequent spectral information with some or all of the original spectral information to obtain a measure of their spectral deviation; and determining an indication of wholesomeness of the unopened item of packaged aliment in dependence of the obtained measure of spectral deviation.

    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: An apparatus for spectrophotometric analysis comprises a sample reception surface, which is arranged to receive a sample to be analysed, and a sample contacting surface, which is moveable in relation to the sample reception surface such that it may be brought to a first position, where the surfaces are sufficiently far apart to allow the sample to be placed on the sample reception surface, and a second position, where the sample contacting surface makes contact with the sample and compresses the sample. The apparatus further comprises a sample thickness controller, which is arranged to control the distance between the sample reception surface and the sample contacting surface in the second position of the sample contacting surface, such that a sample thickness between the surfaces may be shifted for obtaining at least two measurements of the sample at different optical path lengths through the sample.
