MALDI-TOFMS, which can measure the polymer distribution in singly-charged ions, helps in the characterization of synthetic polymers. The combination of high-mass resolution MALDI-TOFMS and the Kendrick mass defect (KMD) method has improved the efficiency of the analysis of complex polymer mass spectra. However, there is still room for consideration of methods for comparing and classifying many complex mass spectra for purposes such as quality control. In this presentation, we compared statistical analysis results using KMD plots and mass spectra to extract characteristic patterns to simplify summarizing and classifying data.
