Abstract Ethonium, an antimicrobial chemotherapeutic agent, was investigated by mass spectrometry (MS) under various ionization conditions: electron impact, field ionization, field desorption (FD) and fast atom ionization. FDMS was found to be the most suitable procedure for ethonium identification. Relation of the ED mass spectra to the distance between the nitrogen atoms in bis-quaternary ammonium compounds is discussed. It was shown that the most intensive ions with m/z 499, 315 in the FD mass spectra corresponded to the ethonium specific fragmentation and their occurrence in the spectra could serve as a sufficient criterion useful in qualitative and quantitative assay of the drug in the sample.
