Ion ionization energy
Web14 apr. 2024 · Positive- and negative-ion mode ESI selectively ionize basic and acidic compounds in petroleum. In order to fully understand the CID and thermal reaction behavior of polar species in heavy petroleum, positive- and negative-ion ESI FT-ICR MS were both used in the present research. WebThermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are ionized. Thermal ionization is used to make simple ion sources, for mass spectrometry and for generating ion beams. [1]
