Abstract:
1. A computer implemented method of performing non-targeted analysis on data collected on a plurality of detected components from a plurality of samples, to identify components of interest, comprising the steps of: a) building a database of said data collected on a plurality of detected components from a plurality of samples, wherein each data record for each of said detected components from each of said samples includes a first spectrographic data characteristic of said component and a second spectrographic data characteristic of the amount of said component; b) generating an ordered pair (X, Y) of data for each of the components contained in said database where X is correlated with said first spectrographic data and Y is correlated with said second spectrographic data; c) associating each of said ordered pairs (X, Y) with one or more secondary data elements of identifying data; d) comparing all of said data elements X contained in the database and determining which data elements X are substantially the same; e) from said data elements X which were so determined to be substantially the same, calculating the average value of data element X for each such data element X; f) from data elements X which were not determined to be substantially the same, calculating the average value of data element X for each such data element X; g) generating a two dimensional array of said data wherein one axis is defined by a plurality of said averaged data elements X so determined in steps (e) and (f) and the other axis is defined by at least one secondary data element, and each array cell described by the intersection of such axes contains data specific to one or both of the axes so defined and selected from the group consisting of: data element X, data element Y, and secondary data elements of identifying data; and h) comparing elements of said two dimensional array to identify differences between said samples, said differences identifying components of interest.
