| 摘要 |
<p>The invention proposes a method of tandem mass spectrometry for use in a mass spectrometer having a known characteristic function of mass-to-charge ratios of ions to be analysed, wherein it comprises the following steps: - providing a primary charged ions source to be analysed, - acquiring different spectra, one as primary ion spectrum, one as dissociation spectrum without ionized neutral fragments and one as dissociation spectrum with ionized neutral fragments, - determining potential pairs, - computing to identify from amongst said potential pairs, using a proximity criterion, each real pair of charged fragment peaks corresponding to primary ions by comparing which one of the potential pairs of values corresponds to a real dissociation mass peak pair in the dissociation mass spectrum produced with ionized neutral fragments. - generating dissociation mass spectra corresponding respectively to said parent primary ions of interest, comprising said real pairs of dissociation mass peaks identified.</p> |
