Currently, JASON SMILEQ supports the generation of two types of analytical reports based on quantitative analysis results. These reports offer comprehensive insights into the interpretation of quantitative data. This application note covers the following: Building on the findings from Part 1. Evaluation of Uncertainty Factors, it expands into variance analysis to provide a more detailed examination of uncertainty factors and their contributions. Furthermore, Part 3 leverages the insights from both Part 1 and Part 2 to present a deeper analysis of uncertainty factors.

Currently, JASON SMILEQ supports the generation of two types of analytical reports based on quantitative analysis results. These reports offer comprehensive insights into the interpretation of quantitative data. As part of the background, this application note provides an overview of the factors contributing to uncertainty and their significance in quantitative NMR analysis. The main focus lies in presenting an overview of SMILEQ reports and offering an in-depth explanation of the 'Uncertainty Report.' Parts 2 and 3 delve deeper into the findings presented in the Uncertainty Report, transitioning into variance analysis to examine uncertainties arising from factors not covered in the report. Additionally, these sections showcase examples illustrating the application of variance analysis and the evaluation of uncertainty factors.

Headspace solid-phase microextraction (SPME) was used to trap and concentrate trace volatiles from two polymer samples for analysis by combined gas chromatography/mass spectrometry (GC-MS) using the HTA 2800T combination autosampler and the JEOL UltraQuad™ SQ-Zeta single quadrupole GC-MS system.

In this MSTips, we report the analysis results of aroma components in peach juice using a gas chromatography quadrupole mass spectrometer (GC-QMS) and msFineAnalysis iQ. Additionally, we present the results of target analysis of γ-lactones, aroma components characteristic of peaches, using the new functionality target analysis function.

Thermal desorption (TD) and pyrolysis gas chromatography-mass spectrometry (py-GC-MS) identified the source of an unexpected contaminant introduced during sample preparation.

Field Desorption (FD) is demonstrated as a useful way to obtain mass spectra for many organometallic complexes.

JEOL developed msFineAnalysis as qualitative analysis software for our gas chromatograph time of flight mass spectrometer (GC-TOFMS). We implemented deconvolution detection, variance component analysis, and other features in the software through updates. We have recently developed a new version of the series called msFineAnalysis AI. msFineAnalysis AI is equipped with a structural analysis method using artificial intelligence (AI), called "AI structural analysis." AI structural analysis enables the identification of molecular formulas as well as structural formulas of compounds that are not registered in the NIST 20 library (unknown compounds).

This is an application notebook that summaries a wide variety of applications of the JMS-S3000 SpiralTOF™ series MALDI-TOFMS that are useful as a shared instrument at universities.

Dedicated SIM/SRM data quantitative analysis software for Dioxins.

Boroxine cages are nanometer-sized covalent cage-like molecules that utilize beroxine formation reactions. Such molecular-sized hollow structures can contain other molecules. Encapsulated molecules sometimes change their properties significantly, and various applications using them are being investigated. One of the methods for confirming the synthesis of boroxine cages is mass spectrometry, and MALDI-TOFMS is suitable because it can ionize a wide range of compounds mainly as single-charge ions. The JMS-S3000 SpiralTOF™ achieves a long flight distance of 17 m due to its unique spiral ion trajectory, and can measure low-molecular-weight compounds ionized by the MALDI method with high mass resolution and high mass accuracy. In this report, we report the accurate mass measurement of the boroxine caged 12-mer.
