合成高分子のイメージング質量分析のための平均分子量・多分散度を指標とした可視化方法
Matrix assisted laser desorption/ionization (MALDI) mass spectrometry is a powerful tool for the analysis of synthetic polymers. This technique can determine molecular weight distributions, which are often expressed as average molecular weight and polydispersity indices. MALDI mass spectrometry imaging (MSI), which is most commonly applied to biological applications, is typically used to visualize the location of target compounds on a surface by extracting the mass images for specific molecular weights. However, given the molecular weight distributions for synthetic polymers, it would be more useful to view the mass images based on specific degrees of polymerization. In this report, we have investigated a MSI visualization method for synthetic polymers that uses average molecular weight and polydispersity indices.
