摘要: An accumulating ion source for a mass spectrometer that includes sample injector (328) introducing vapors into an ionization space (115) and electron emitter (102) emitting continuous beam (104) the to generate analyte ions. The further first second electrodes (108a, 108b) arranged spaced apart in ions substantially therebetween. receive periodic extraction energy potentials accelerate packets of from along axis. orthogonal accelerator (140) receives axis periodically accelerates A time delay between acceleration each respective packet provides proportional range
