MION2 brings to the analysis:
Reagent ion and polarity switching in seconds
the injection of ions can be turned off quasi-instantaneously by controlling the electrode voltages
Possibility to use wide range of reagent ions
Br-, NO3-, NH4+, C4H12N+, I-, H3O+, C3H7O+
Ionization at ambient pressure
prevents the dilution of a sample
Only charged reagent ions are injected
into ion-molecule mixing region, preventing neutral reagent molecules from affecting the sample
Sampling of ambient ions
when voltages are turned off
Negligible fragmentation
owing to soft adduct-forming ionization
