The results of investigation of decamethoxinum on matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometer using 2,5-dihydroxybenzoic acid (DHB) matrix were presented. The MALDI mass spectra were obtained in the linear, reflectron and post source decay (PSD) modes. The spectra reveal diagnostic quasimol. ions of the decamethoxinum [Cat·Cl]+ and [Cat-H]+. The PSD data confirm that the pathways of unimol. decay of the [Cat·Cl]+ ions in the gas phase coincide with those of the salt thermal degradation via dequaternization; this agrees with the data obtained earlier with the use of secondary ion mass spectrometry. Abundant clusters containing Cat2+ and anions those originate from the DHB matrix were observed, and it was suggested that they were stabilized either by the electrostatic interactions with the carboxylic group (carboxylate anion) of DHB or due to the cation-π interactions with the DHB aromatic ring.
