Identification and elimination of chemical noise for an improved ms - and ms / ms - analysis

摘要

It is a process for the mass spectrometry is disclosed, in which ions masses are analyzed and masses spectrum data are obtained and is of interest to be determined output - or precursor ions. In the process are also first adduct - or chemical artefact ions is determined, the mass - / charge condition, a substantially linear relationship with the mass - / charge ratio of the output - or precursor ions, and the first adduct - or chemical artefact ions from the mass spectrum data eliminated or weakened.
