In this work, we used direct probe field desorption (FD) of crude oil (a very complex mixture) to monitor the effects of improved resolution. Additionally, the JEOL msRepeatFinder software was used to examine the crude oil data by using Kendrick mass defect (KMD) plots in order to more clearly visualize the effects of improved mass resolution on the analysis results.

In this work, we used the thermal decomposition of an acrylic resin to evaluate how improved mass accuracy can affect the analysis results for a complex sample. Additionally, the msFineAnalysis version 3 software included with the JMS-T2000GC was used to quickly determine the impact of improved mass accuracy on the qualitative analysis results.

In this work, we used Py-GC-QMS and high-resolution MALDI-TOFMS to evaluate the effects of UV irradiation on polystyrene (PS).

When performing simultaneous analysis of pesticide residues in food, there are many items to be set for each compound, and creating new measurement conditions requires a lot of time. In this paper, SRM Compound Data File" and "SRM Optimization Tool" are introduced.

JEOL has developed a filament for low-vacuum that utilizes a new wire with enhanced oxidation resistance to enable stable measurement by the EI method in an oxygen atmosphere. In this study, the gases evolved from polystyrene at various oxygen concentrations were measured by TG/DTA-MS using a filament for low-vacuum.

In this report, we verify that the end group analysis of polystyrene by TDP-DART-MS examined in Reference [1] is possible by the TDP device ionRocket (BioChromato) and AccuTOF™ LC-plus 4G.

In this work, we examine the effects of nitrogen carrier gas on the performance of our GC-TOFMS for high resolution, accurate mass analysis.

In the fall of 2019, SpiralTOF™ was renewed to "SpiralTOF™-plus" with enhanced mass spectrometry imaging capabilities while maintaining the feature of high mass-resolving power. This report introduces the features of SpiralTOF™-plus and its advantages in actual analysis.

We have attempted a rapid analysis of Py-GC/MS method using JMS-Q1500GC by optimizing Py and GC oven conditions, and achieved a cycle time of 14.75 min per measurement. Here, we report the results.

In this application note, we identified the additives and their distribution within a commercially available molded polymer by using GCxGC/HRTOFMS with pyrolysis (PY/GCxGC/HRTOFMS).
