摘要：

A simple, two-dimensional, 90° electrostatic quadrupole deflector has been developed. This device allows an ion source to be located off the axis of a quadrupole mass spectrometer, or permits two or three ion sources to be interfaced to a common mass analyzer. A number of possible quadrupole deflector geometries have been studied by computer simulation of ion trajectories. The experimentally determined ion transmission and energy dispersive properties of the quadrupole deflector are described. © 1990, American Vacuum Society. All rights reserved.
