Abstract
In an electric charge adjusting method and mass spectrometer, tandem linear ion traps are employed such that charge-reducing reactions occur in only one of the linear ion traps. An ion reaching a given charge value is selectively moved to another linear ion trap. Through MS/MS mass analysis, the structure of a biomolecule is analyzed very efficiently with high sensitivity via a simple analysis.
