method and mass spectrometer for massenspektroskopischen or mass spectrometric study of particles

摘要

the invention concerns a procedure and a mass spectrometer or to massenspektroskopischen mass spectrometric study of particles. the particles are $a, according to their different masses in a separation system separately.$a for the reduction of nachweisfehlern by dispersed particles is a korrektureinrichtung a nachweiseinrichtung vorgeordnet, a bremspotential builds to particles with an energy loss by diffusion control.$a to improve the korrektureinrichtung is the invention of a further, preferably combined correction, through which the particles are selected bewegungsrichtungsabhu00e4ngig. $a, the erfindungsgemu00e4u00dfe mass spectrometer has in at least a bremselektrode preference and qua drupollinse.
