Zusammenfassung:A method of reducing fragmentation of ions generated from a sample during transport of the ions through an ion transport apparatus that comprises an ion funnel portion, comprises: applying a selected DC potential difference between an outlet end of the ion transport apparatus and an exit ion lens that is disposed adjacent to the outlet end, wherein a sign of the selected DC potential difference is chosen so as to accelerate the ions from the outlet end of the ion transport apparatus towards and through the exit ion lens.
