Abstract
Time-of-flight secondary ion mass spectrometry was carried out to analyze a commercially available propanedioic acid (malonic acid) powder. Positive and negative polarity ion spectra were obtained using a 25 keV Bi3+ ion beam rastered over areas of 50 x 50 mu m(2). The main observed fragments were the protonated molecule [M+H](+) at 105 Da and the deprotonated molecule [M-H](-) at 103 Da with their respective oligomers. Published by the AVS.
