Method and device for characterising an analyte

摘要: A method and apparatus are provided for characterizing a product sample example in comparison to reference using sensor such as gas chromatograph or MOS sensor. This characterization may comprise an indication of whether not the conforms quality criterion. The output measurements is compared maximum minimum value curves, which be derived from sample, whereby adjacent samples outside envelope defined by these values grouped together. dissimilarity index determined anomalous whole, on per group basis. groups classified depending shape they describe, particular presence, not, peaks, correspondingly corresponding part envelope. These determinations then used basis conformity indication, also attempting identify cause any anomalies, identification foreign components.
