Abstract

AbstractA number of commercial β‐lactam antibiotics are investigated by means of cesium ion (Cs+) bombardment in the kinetic energy range 2–35 keV. The relative intensities of the protonated molecules, as well as some of the major fragment ions, are monitored as a function of the Cs+ kinetic energy. The dependence of the intact protonated molecule:fragment ion ratios on the primary‐ion kinetic energy is evident in some of the spectra investigated. An attempt is made to interpret these results in terms of existing secondary‐ion mass spectrometry data which have been obtained in a different kinetic energy range.
