Experimental Samples in this report were measured with the AccuTOF-DART™ mass spectrometer. Similar procedures can be used with other members of the AccuTOF mass spectrometer family. Calibrated mass spectra were centroided and saved as JEOL-DX (JCAMP) text files. These text files were processed with the Elemental Composition Workshop from the Mass Spec Tools™ software suite distributed with AccuTOF mass spectrometers. The program permits automated isotope matching for measured mass spectra and provides a visual comparison between the measured and theoretical isotopic abundances for each hit (Figure 1).
