Esi-tof-ms spectrum
Web3-Pyridinylboronate, a zwitterionic boronic acid, displayed effective in situ ESI for reversible covalent tagging of saccharides in both cation and anion modes. The ion mobilities of thus-generated ions were examined with the Bruker timsTOF fleX instrument. Nine disaccharides were examined using this method. WebSimilarly to MALDI-TOF MS, electrospray ionization mass spectrometry (ESI-MS) is also a soft ionization method which provides a complete picture of the absolute molecular weight of the analyte. In 1999, Angelis et al. characterized in vitro models of synthetic lignin using ESI-MS combined with high performance liquid chromatography.
