Atmospheric pressure photoionization (APPI)
Direct ionization of molecules at atmospheric pressure by electron detachment induced by photons forming M+., or atmospheric pressure chemical ionization in which the reactant ions are generated by photoionization of suitable dopant species and subsequent ion/molecule reactions of their molecular ions.
