Analysis of Advanced materials by FD-FI using AccuTOF GC (Part I)
Introduction
Field Ionization (FI) is a soft ionization method that ionizes analytes by electron tunneling from analyte molecules to a solid surface (emitter) in a high electric field. The vaporized analyte molecules are introduced into the proximity of the emitter in order for ionization to occur. In this work, we analyzed functional monomers (building blocks for functional polymers) by GC/EI and GC/FI methods and then compared the resulting mass spectra.
