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.

Cryo electron microscope, whose resolution can even observe inside of biomolecules, molecular structure analysis instruments such as electron diffraction, nuclear magnetic resonance, mass spectrometry, that support molecular biology and drug discovery. JEOL provides a variety of research instruments that support life science.

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.

XtaLAB Synergy-ED allows molecular structural analysis of submicron particles of laboratory chemicals. In addition, the comprehensive analysis by JEOL mass spectrometer (MS) and nuclear magnetic resonance (NMR) spectrometer provides details of chemical structure information for molecular structure determination.
