摘要：There is disclosed a method of selectively extracting ions comprising the stepsof: providing a supply of ions in a body of gas; generating a ponderomotive ion trappingpotential generally along an axis; generating further potentials to provide an effectivepotential which prevents ions from being extracted from an extraction region; trappingions in said effective potential; and selectively extracting ions of a predetermined m/zratio or ion mobility from the extraction region; in which the characteristics of theeffective potential which prevent ions from being extracted from the extraction regionare caused, at least in part, by the generation of the ponderomotive effetive ion trappingpotential.
