Abstract: Determination of Analytes in a Sample Matrix by Solvent Extraction A method for the assay of one or more analytes in a sample matrix comprising the steps of: performing analyte extraction on the sample matrix, said analyte extraction comprising combining the sample matrix with a solvent for an extraction period which is less than that required for reaching equilibrium; and separating the analyte containing solvent from the sample matrix; next measuring a level of analyte present in the separated solvent; and then applying in a computer a calibration by which is established a mathematical relationship between levels of analyte extracted from each of a plurality of reference samples by means of the process employed above in the extraction for the sample matrix and a reference value of the levels of analyte for each reference sample to thereby derive a measure of the level of analyte in the sample matrix. Specifically a method to determine the amount of mycotoxins in cereal grain, especially OTA (ochratoxin A) and DON (deoxynivalenol) by mixing with a solvent comprising water alcohol mixture, with 20-40% ethanol by volume.

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 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).
