System and method for modified gas chromatographic data analysis

A self-reliant gas chromatography system for analysis of gas chromatographic data, the system comprising:

• a chromatographic separation column for separating a sample into a plurality of constituents, said chromatographic separation column includes an inlet and an outlet;
• a sample delivery device coupled with said chromatographic separation column at said inlet, for providing said sample to said chromatographic separation column;
• a detector in communication with said outlet of said chromatographic separation column for detecting at least a portion of said plurality of constituents, said detector producing a signal that includes said gas chromatographic data corresponding to characteristics of the detected said at least a portion of said sample, said gas chromatographic data including at least one observed chromatographic peak characterized by at least one temporal attribute and at least one observed shape attribute;
• a memory device for storing said gas chromatographic data and a plurality of gas chromatographic reference data, said gas chromatographic reference data including at least one reference chromatographic peak characterized by at least one temporal attribute and at least one reference shape attribute;
• and
• a processor coupled with said detector and with said memory device, said processor determines respectively, for said at least one observed chromatographic peak, at least one parameter in a modeling function, such to substantially fit said modeling function to said at least one observed chromatographic peak, said at least one parameter includes at least one of said at least one shape attribute, said processor associates respectively, for said at least one observed chromatographic peak said at least one reference chromatographic peak according to:
• a degree of correspondence between an observed value of said at least one shape attribute of said at least one observed chromatographic peak, and a reference value of respective said at least one shape attribute of said at least one reference chromatographic peak;
• and
• a degree of correspondence between an observed value of said at least one temporal attribute of said at least one observed chromatographic peak, and a reference value of respective said at least one reference temporal attribute of said at least one reference chromatographic peak;
• and
• said processor estimates respectively, for said at least one observed chromatographic peak, said measure of match according to a degree of fitness between said observed value and respective said reference value of said at least one shape attribute.
