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: 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.

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.
