Using Volcano Plots to Compare Vinyl Acetate Resin Samples Measured by Pyrolysis GC-MS March 5, 2020 AccuTOF™ GC, Application Note, Mass Spectrometry (MS), Materials 0 Introduction Advances in mass spectrometry are enabling analysis of micro samples and unknown components that were not observable before. As the volume of information acquired from mass spectrometry increases, researchers are calling for simple techniques to analyze the numerous components observed, and as a result, there is a rise in demand for comprehensive analytical techniques including multiple classification analysis. In this work, we analyzed 2 samples in a high resolution GC-TOFMS, using EI, the most widely used ionization technique for GC-MS, and compared the data acquired by using a comprehensive analytical technique. Experiment As model samples, 6 commercial vinyl acetate resins (adhesives) were used. A gas chromatography time-of-flight mass spectrometer (GC-TOFMS) was used for the measurements. Since emulsion samples including adhesives are difficult to analyze without preliminary treatment, the samples were subjected to pyrolysis. Also, a column shorter than a typical GC column was used along with a Fast GC temperature sequence to speed up the measurement process. The data acquired was examined using SpectralWorks Analyzer Pro, and 2 samples were compared by the Volcano Plot. Table 1 shows the pyrolysis fast GC/TOFMS measurement conditions.

Integrated Analysis of a Vinyl Acetate Resin using Pyrolysis GC-HRMS - MSTips 275 In this work, we introduce the msFineAnalysis software and use it to automatically combine data acquired by GC/EI and GC/soft ionization for the qualitative analysis of compounds produced by the pyrolysis of a vinyl acetate resin. GC-TOFMS Application: Natural Polymer Analysis by using Pyrolysis-GCxGC-MS - "Urushi" analysis with GCxGC/EI and GCxGC/PI A Japanese lacquer film called "Urushi" is a natural polymer that has been used as a paint and adhesive for living-wares and craft-wares for approximately 8,000 years. "Urushi" has a complex structure that researchers are trying to understand using pyrolysis-gas chromatograph/mass spectrometer (Py/GC/MS) system. Recently, we developed a new gas chromatograph/high resolution time-of-flight mass spectrometer (GC/HR-TOFMS) system that can be used for comprehensive two-dimensional GC (GCxGC) measurements. Additionally, we have developed a unique combination electron ionization/photoionization (EI/PI) ion source that can be used with this GC/HR-TOFMS system. In this work, we measured "Urushi" samples using this unique Py/GCxGC/HR-TOFMS system in combination with our new combination EI/PI ion source.

Integrated Analysis of an Acrylic Resin using msFineAnalysis v2 - MSTips 300 In 2018, msFineAnalysis Ver.1 software was released in which data acquired by EI, soft ionization, and accurate mass measurements were automatically integrated to generate a qualitative report for samples measured by these techniques with GC-MS. Recently, msFineAnalysis Ver.2 was introduced as an enhanced version with additional features. In this work, we will describe the changes in Ver.2, which now includes chromatographic deconvolution, and present applications using the new features. Analyzing a Specific Component using Group Analysis of msFineAnalysis Ver. 2 - MSTips 303 In 2018, we announced the msFineAnalysis software which was designed to automatically integrate two types of data acquired by EI and soft ionization. Recently, we developed msFineAnalysis Version 2, an enhanced version with additional features. msFineAnalysis Version 2 incorporates two new features: Chromatographic Deconvolution and Group Analysis. In this work, we use the group analysis capabilities of the software to evaluate the pyrolysis GC-MS results for a vinyl acetate resin. Showing 0 Comment Comments are closed.
