Preferred Label : chemical ionization;
Detailed label : chemical ionization in mass spectrometry;
IUPAC definition : This concerns the process whereby new ionization species are formed when gaseous molecules
interact with ions. The process may involve transfer of an electron, 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 is involved, the term
negative ion chemical ionization should be used; note that negative ion formation
by attachment of a free electron does not fall within this definition. Chemical ionization
and chemi-ionization are two terms which should not be used interchangeably.;
