Novel ionization processes provide gas-phase ions of a wide variety of materials using MS. These simple and sensitive methods operate from solution or a solid matrix. Both manual and automated platforms are described that allow rapid switching between the ionization methods of MAI, SAI, vSAI, and conventional ESI.
An important attribute of a novel ionization process for use in mass spectrometry (MS) is its simplicity and flexibility to be hyphenated to conventional liquid-based separation methods.
