FIELD: chemistry.
SUBSTANCE: method involves separation of ions in a linear radio-frequency trap with a gas stream along the axis of this trap based on differences in resistance of ions to collision-induced dissociation. The important feature is detection of induced signals from rotating or oscillating ions under the effect of a non-resonance rotating field which brings the analysed ions out of the gas stream, as well as under the effect of fields which are close to resonant fields on frequency, which excite harmonic motion of ions with selected m/z values. The mass spectrum of product ions during collision-induced dissociation can be recorded using a mass analyser which is interfaced with the trap, particularly a time-of-flight mass analyser with orthogonal ion input.
EFFECT: mass-spectrometric separation and obtaining quantitative information on analysed compounds.
