In this study, we describe an optimized DDA method for peptide PTM analysis using the UNIFI Scientific Information System with the Vion IMS QTof MS especially for low abundant peptides with interference from co-eluting peptides. The high sensitivity and high dynamic range specifications of the Vion IMS QTof enable high quality MS/MS data for low abundant peptides and accurate quantitation. MSE combined DDA methods meet all the requirements in peptide mapping qualitatively and quantitatively.
