FIELD: hyperboloid mass spectrometry; development of high-sensitivity and high-resolution devices of this type.
SUBSTANCE: proposed method for introducing ions to be analyzed includes introduction of ions produced beyond working space into working space of analyzer incorporated in hyperboloid mass-spectrometer of three-dimensional trap type near radial plane through one or more channels provided in circular electrode at certain angle to straight line interconnecting inlet point and center of analyzer electrode system; ions being analyzed are forced in working space of analyzer over paths whose envelopes function as circumferences by controlling angle and relative rate of introduction using relevant correlations.
EFFECT: effective capture of introduced ions enhanced by more than order of magnitude.
