MASS SPECTROMETER FOR MACROMOLECULE ANALYSIS Russian patent published in 2008 - IPC H01J49/40 G01N27/62 

FIELD: physics.

SUBSTANCE: mass spectrometer contains holder with analysed substance, ionisator and supplier of macromolecules to mass analyser, and detector. Mass analyser is connected to holder with analysed substance, and detector is based on matrix of micromechanical cantilevers providing determination of interaction time point and point where accelerated macromolecule contacts with petal surface of micromechanical cantilever, providing macromolecule pulse transfer to micromechanical cantilever petal, and following deviation of petal by the distance determined by weight and energy of macromolecule. Thus detector is implemented within consistently optically connected emitting sources, collimating optics, micromechanical cantilever matrix, projecting optics and photodetector, while micromechanical cantilever matrix thereof is designed as detector substrate where micromechanical cantilevers are mounted, thus micromechanical cantilever is designed as part of leg, arm, reflecting layer. Micromechanical cantilever matrix is multielement.

EFFECT: increased integrated sensitivity within wide range of macromolecule weights.
