This introduces examples of chemical structure analysis of surfactants that combine precise mass measurements using high-resolution MALDI-MS with new analytical methods.
The technical information magazine The TRC News provides the latest information on analytical techniques that are useful for research and development, solving production troubles, and quality control. [Abstract] In recent years, with the spread of high-resolution mass spectrometers, the amount of information obtained from mass spectrometry has significantly increased, while the time required for analysis has also risen. In response, efforts are being made to efficiently analyze by grasping the overall picture of mass spectra using new analytical methods. This article presents examples of chemical structure analysis of surfactants combining precise mass measurements using high-resolution MALDI-MS and new analytical methods, as well as a case study on tracking the reactions of epoxy resins. [Table of Contents] 1. Introduction 2. Kendrick Mass Defect (KMD) Analysis 3. Chemical Structure Analysis of Surfactants 4. Tracking the Curing Reactions of Epoxy Resins 5. Conclusion
