Abstract

See full text

A time-of-flight mass spectrometer (TOF-MS) utilizes a multi-channel ion detector to detect ions traveling in separate flight paths, spatially dispersed along a drift axis and/or a transverse axis, in a flight tube of a TOF analyzer. The ion beams may be dispersed by drift energy, deflection along the drift and/or transverse axis, ion mass, or a combination of two or more of the foregoing. The dispersion may be carried out before, at, or after an ion accelerator of the TOF analyzer. Ion packets may be accelerated into the flight tube at a multi-pulse firing rate. Tandem MS may be implemented on parallel ion beams simultaneously.
