摘要：
In the field of mass spectrometry, a method of obtaining a mass spectrum enriched with fragment ions while retaining the precursor ion. The technique includes varying the collision energy experienced by the precursor ion such that a range of fragmentations occur. Related methods are also disclosed for obtaining MS, MS2, MS3 and MSn spectra which are enriched with fragment ions.
