Flowing afterglow ion sources usually consist of a dielectric discharge that gases are channeled through to be excited and thus made into plasma. Flowing afterglow ion sources can be coupled with a selected-ion flow-tube for selection of reactant ions. When this ion source is coupled with mass spectrometry it is referred to as flowing afterglow mass spectrometry.
