Mass to charge ratio of ions

Webisomers of Asp were analyzed by charge transfer dissociation (CTD) mass spectrometry to identify spectral features that could discriminate between the different isomers. For the four isomers of Asp in three model peptides, CTD produced diagnostic ions of the form c+57 on the N-terminal side of iso-Asp residues, but not on the N-terminal side of Asp WebObservation and implications of high mass-to-charge ratio ions from electrospray ionization mass spectrometry J Am Soc Mass Spectrom. 1993 Jul;4 (7):536-45. doi: …

WebMass spectrometry consists of three basic steps: “ionization”, “mass separation”, and “detection”. Ionization is a process by which molecules become charged (charged molecules are called ions). The generated ions have a physical quantity called the mass-to-charge ratio, i.e. the mass of the ion divided by its charge.
