Methods and apparatuses for the analysis of mass spectroscopic (MS) data as well as ultraviolet (UV) absorption data. In particular, described herein are tools and methods to assist in generating annotated peptide maps from a raw MS data.

Apparatuses and methods for annotated peptide mapping

This invention relates to graphical user-interactive displays for use in MS-based analysis of protein impurities, as well as methods and software for generating and using such. One aspect provides a user-interactive display comprising an extracted mass chromatogram (XIC), an MS1 spectrum and an MS2 spectrum, all simultaneously representing a user-selected peptide. Another aspect provides a user interactive display simultaneously presenting paired spectra (XIC, MS1 and/or MS2) for a variant peptide and its corresponding wildtype counterpart.
