Kurzfassung:
Time-of-flight secondary ion mass spectrometry was carried out to analyze a commercially available heptanedioic acid (pimelic acid) powder. Positive and negative polarity ion spectra were obtained using a 25 keV Bi3+ ion beam rastered over areas of 50 × 50 μm2. The main observed fragments were the protonated molecule [M+H]+ at 105 u and the deprotonated molecule [M-H] − at 103 Da with their respective oligomers.
