Each com-pound had a unique fragmentation pattern composed of a series of split molecular ions. The mass–charge ratios and amount of the ions were compared to a standard mass chromatogram in the LECO-Fiehn Rtx5 mass spectra library in the Chroma TOF4.3X Software. For each peak, the software generated a list ofsimilarities
after comparing them with every substance that was in the LECO-Fiehn Rtx5 library [13]. Peaks that had more than 700 similarities were chosen for further research.
