FIELD: spectrometry.
SUBSTANCE: invention relates to spectrometry. Ion mobility spectrometer comprises an ionizer for sample ionisation; a detector separated from the ionizer by a drift chamber, along which the ions can move from the ionizer to the detector; a gate for controlling movement of ions from an ionizer into a drift chamber; an ion modifier installed between the ionizer and the detector and comprising a first electrode and a second electrode; and voltage source, configured for application, between the first electrode and the second electrode, voltage variable in time, wherein frequency of voltage varied in time is at least 2.5 MHz.
EFFECT: technical result is higher efficiency of modifying ions.
