Abstract

In the interpretation step of mass spectra obtained from synthetic polymers, isotope peaks are typically intense and cannot be ignored, especially in the higher mass range. To reduce the complexity of the spectra, deisotope processing is used. In this study, a deisotope processing method that is effective even for mixtures of different types of polymers is investigated.
