Abstract
Provided is a mass spectroscope employing electron capture dissociation wherein the peak number of detectable fragment ions is increased. The mass spectroscope comprises an ion source (2) for generating ions from a sample, an ion trap (3) for storing and selecting ions, an ion dissociation section (4) performing electron capture dissociation on ions, and a time-of-flight mass spectrometry section (7) performing mass spectrometry on ions, wherein the reaction time of electron capture dissociation is variable depending on the valence of ions subjected to mass spectrometry.
