Abstract: A method of determining a constituent related sample property of a multi-constituent sample comprising: subjecting the sample to a perturbation selected to induce a time dependent change in measurement data associated with a constituent related to the sample property to be determined; recording a time-series of measurement data following subjecting the sample to the perturbation; and determining the sample property from the application to the recorded time-series of measurement data of a calibration correlating the sample property with time-series of measurement data, said calibration being empirically derived from chemometric time-series modelling of time-series measurement data recorded for each of a plurality of reference samples following subjecting each reference sample to the perturbation, each reference sample having a different known values of the sample property.

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 LIBS analysis system comprises a focusing lens arrangement having a focal plane; a laser for propagating a laser beam through the focusing lens arrangement to be focused at the focal plane; a detector for generating an output that is proportional to an intensity of incident electromagnetic radiation that is incident on the detector; a translation mechanism configured to cause a relative movement of the sample holder and the focusing lens arrangement to vary a position of the focal plane along the optical path with respect to the sample holder; and a controller configured to automatically control the translation mechanism to cause the relative movement of the sample holder and the focusing lens arrangement to achieve an optimum position at which the focal plane and an analysis region of the upper surface intersecting the optical path are at or are close to coincidence.

Abstract: A system for accepting or rejecting a container containing a meat batch comprises a reader and a controller cooperating to effect the acceptance or the rejection of the meat batch. The reader is configured to interrogate a machine readable tag attached to the container to retrieve information stored thereon into the controller which is configured to respond to the information retrieved by the reader to access batch information comprising at least information indicative of a fat content of the meat batch, to compare the batch information with a criterion of a recipe related to a target fat content to determine a suitability of the meat batch for inclusion in a mix meeting the recipe, and to generate a control signal dependent the determination usable to effect acceptance or rejection of the meat batch as appropriate to the determination.

Abstract: A method of standardizing an output of an electrical property sensor includes calculating a reference magnitude (Condr) of an electrical property of an electrically conductive liquid, based on obtaining, by a spectrometer, spectral data resulting from an interaction of light with the electrically conductive liquid, and applying, in a data processor, a mathematical model to the spectral data to calculate the reference magnitude (Condr) of the electrical property, wherein the mathematical model links the spectral data to magnitudes of the electrical property; comparing, in the data processor, a measured magnitude (Condm) of the electrical property of the electrically conductive liquid with a reference magnitude (Condr) of the electrical property, wherein the measured magnitude (Condm) of the electrical property is obtained with the electrical property sensor; determining, in the data processor, a standardization factor (F) dependent on a ratio of the reference magnitude (Condr) and the measured magnitude (Condm).
