Pyrolysis‑GC‑MS provides structural information on substructures originating from monomers and end groups. While many detected pyrolysis products are not registered in the NIST library, automated analysis be achieved using AI structure analysis with msFineAnalysis AI.

In this report, we attempt to improve the image quality of extracted mass images using the FINE-AI Filter, which was developed by applying a machine-learning model for noise filtering—originally created from secondary electron images obtained by scanning electron microscopy (SEM)—to MALDI-MSI.

In this report, we attempted end group analysis using high-precision MALDI-TOFMS after SEC fractionation of polycarbonate (PC) with high polydispersity.

This report introduces a phase analysis method using vertex component analysis (VCA). Furthermore, a machine learning-based noise reduction method (FINE-AI Filter) was applied as a preprocessing step.

Mass spectrometry (MS) is a method that can perform qualitative and quantitative analyses of polymers and additives contained in polymeric materials by ionizing them and analyzing their molecular masses. There are multiple ionization methods, mass spectrometer types, and data analysis technologies, and it is possible to obtain more comprehensive information by combining them. In this guidebook, we will introduce polymeric materials analysis solutions that make full use of JEOL's high-performance mass spectrometers.

XtaLAB Synergy-ED allows molecular structure analysis of micro-crystal. This feature is quite effective in the difficult case of crystallization, such as transitional metal complexes. Furthermore, the comprehensive analysis using JEOL mass spectrometer (MS) and nuclear magnetic resonance (NMR) provides detailed information for molecular structure determination.

The use of high-mass-resolution MALDI-TOFMS makes it possible to easily identify polymer series due to differences in the composition of repeating units and end groups, and to calculate the molecular weight distribution of each. Using the KMD method, it became possible to easily visualize polymer series contained in complex high-mass-resolution mass spectra. From NMR, we can expect to obtain detailed structural information (random and block structures) of copolymers that are difficult to analyze by MS.
