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 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 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: Compensating for frequency drift of a reference energy source in an FT interferometer based spectrometer instrument may include obtaining data representing a reference interferogram collected in response to a trigger signal having been generated in dependence on the emission frequency of the reference energy source, and subsequently obtaining data representing a target interferogram recorded by the FT interferometer in response to a trigger signal also having been generated in dependence on the emission frequency of the reference energy source in the same manner. The method may further include comparing the obtained data to determine a phase shift between the interferograms in a window in at least one region away from center-burst, and generating a mathematical transform dependent on the determined shift to be subsequently applied to generate data representing a frequency stabilized interferogram of an unknown sample recorded by the FT interferometer.

Abstract: A method of controlling a production process including a process step for the morphological modification of a bio-material matrix comprises obtaining digital input data acquired during each of a plurality of production runs of the process, which input data includes information from radiation within a portion of the electromagnetic or acoustic spectrum having interacted with the matrix at one or more locations within the process together with a process control parameter and production event data for the associated production run; generating in a computer a prediction model from a multivariate analysis of the digital input data, which model links the information directly with one or more of process control parameters, production run events and process control settings; and applying in the computer the prediction model to interacted information obtained from a new production run to generate as an output one or more of a process control parameter a process control event and a predicted production run event for the new production run for use in controlling the production process.

Abstract: In a method for hydrodynamic focusing of a laminar and planar sample fluid flow, a system is provided for analysis and/or sorting of microscopic objects in the sample fluid comprising an optical objective for optical inspection of the microscopic objects. Microscopic objects are conveyed in the laminar flow of the sample fluid, and two laminar and planar flow of sheath fluids are provided. The flow of the sample fluid is hydrodynamically focused at an optical inspection zone of the system by the sheath fluids. Focusing of the flow of the sample fluid is controlled such that all of the microscopic objects in the sample fluid are caused to be conveyed in a common flow direction in one single plane at the inspection zone of the system, and the microscopic objects in the fluid are optically inspected through the optical objective.
