    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 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: An analysis instrument comprises a sample receiving section for receiving samples provided by a plurality of users, an analysis section operable to receive an aliquot of each received sample, perform an analysis of each received aliquot, and generate an output based on the analysis, and a presentation section adapted to present the output in a human discernable format. The analysis instrument further includes an identification section adapted to autonomously generate an identifier unique to each user and each sample provided thereby and to supply each identifier for presentation by the presentation section in a human discernable format together with a portion of the output that corresponds with one or more samples provided by a user to which the identifier is unique. Each identifier consists of one or more graphic symbols, one or more colours, and/or one or more numbers.

    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 method and an instrument for determining a nutritional state of a plant with respect to one or more nutrients is provided. The method comprises the steps of recording a time series of a fluorescence induction signal of a tissue sample of the plant using a fluorometer device to obtain signal data, wherein the time series at least comprises signal data within the rising portion of the fluorescence induction signal, and determining the nutritional state from an empirical model applied to the signal data, wherein the empirical model is based on pre-recorded reference data and relates nutritional states to shape-related features in the progression of the fluorescence induction signal.
