Chemical ionization

From Mass Spec Terms
DRAFT DEFINITION
Chemical ionization

Describes the process whereby new ionized species are formed when gaseous molecules interact with ions. The process may involve transfer of an electron, a proton or other charged species between the reactants. When a positive ion results from chemical ionization the term may be used without qualification. When a negative ion results the term negative ion chemical ionization should be used. Note that this term is not synonymous with chemi-ionization, nor with negative chemical ionization.

Considered between 2004 and 2006 but not included in the 2006 PAC submission
