紫外線照射により劣化させたポリエチレンテレフタレートフィルムのイメージング質量分析と他の分析手法との相関
Matrix assisted laser desorption/ionization (MALDI) mass spectrometry is a powerful tool for the analysis of synthetic polymers. By using MALDI with a high-resolution time-of-flight mass spectrometer, this technique can be used to identify differences in polymer end groups and their molecular weight distributions. Kendrick mass defect (KMD) analysis of this data simplifies the data interpretation, even for complicated mass spectra, by showing an overview of the differences observed within a sample. MALDI mass spectrometry imaging (MSI) is a method for analyzing the spatial distribution of target compounds on a surface—typically proteins, peptides, lipids and drugs. In this report, we combined MALDI-MSI and KMD to analyze a polyethylene terephthalate (PET) film that had been degraded by ultraviolet (UV) irradiation. We also report the correlation with other analytical method such as, scanning electron microscope, pyrolysis gas chromatography mass spectrometry, infrared spectroscopy.
