Claim:
1. A method of extracting spectra from spectroscopic data obtained by a GC/MS analyzer, the spectroscopic data representing a plurality of different compounds, said method comprising the steps of: 1) receiving spectroscopic data from a GC/MS analyzer; 2) removing any signals having a wavelength that is significantly longer than a typical chromatographic peak from the spectroscopic data by processing the spectrographic data in the GC/MS analyzer before the spectrographic data is processed further; and 3) performing deconvolution on the spectroscopic data using the GC/MS analyzer to thereby find peaks and then group peaks into unknown compounds by first smoothing all peaks using a smoothing filter, and then using the three highest points of each peak of a mass as data points, fitting a parabola to the data points in order to find an intensity of the peak and a time of the maximum point of each peak.
