Abstract
Disclosed is an improved method and apparatus for transporting ions from a first pressure region in a mass spectrometer to a second pressure region therein. More specifically, the present invention provides a segmented ion funnel for more efficient use in mass spectrometry (particularly with ionization sources) to transport ions from the first pressure region to the second pressure region.
