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.

This note highlights several key aspects of the SuperCOOL MARVEL probe’s performance that are central to modern NMR spectroscopy, including its sensitivity across multiple nuclei, its robust RF power‑handling capabilities, and its versatility in experiments involving 1H, 19F, and X‑nuclei.

Scalar couplings arise between magnetically active nuclei that interact through chemical bonds. These couplings carry valuable information about molecular structure and conformation. Accurately measuring them, however, can be challenging. To overcome this, several NMR techniques have been developed, one of the most effective being the HECADE-HSQC (Heteronuclear Coupling Analysis via Double-Edited HSQC) experiment introduced by Koźmiński and Nanz.

This is a compendium of organic chemistry related applications notes and JEOL News articles based on the data acquired on JEOL ultra-high mass-resolution MALDI-TOFMS JMS-S3000 SpiralTOF™ series.

msFineAnalysis iQ is automated qualitative analysis software for JEOL JMS-Q1600GC and JMS-TQ4000GC gas chromatograph-quadrupole mass spectrometers that combines EI mass spectral library database (DB) searching, retention index (RI), automatic molecular ion confirmation using soft ionization (SI), and isotopic pattern analysis on the molecular ion for a new type of qualitative analysis called "integrated qualitative analysis".

AccuTOF™ GC-Alpha is a superior time-of-flight mass spectrometer (TOF MS) system that simultaneously accomplishes high-resolution analysis, high mass accuracy and high-speed data acquisition. Equipped with the unique triple ion source EI/FI/FD that supports LIFDI, it offers the ultimate flexibility for GC-MS and direct-insertion MS applications.

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.
