摘要： A method of standardizing an output of an electrical property sensor (300) comprising the steps of: comparing in a data processor a measured magnitude (Condm) of the electrical property of an electrically conductive liquid obtained with the electrical property sensor with a reference magnitude (Condr) of the electrical property (320); and determining in the data processor a standardization factor (F) dependent on a ratio of the reference magnitude (Condr) and the measured magnitude (Condm) (340); wherein there is provided a step of calculating the reference magnitude (Condr) (330) comprising obtaining by a spectrometer spectral data resulting from an interaction of electromagnetic radiation with the electrically conductive liquid (310); and applying in the data processor a mathematical model to the spectral data to calculate the reference magnitude (Condr), which mathematical model links spectral data to magnitude of the electrical property.

摘要： 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.
