Linear ion traps are extremely powerful analytical devices, either deployed as stand-alone mass spectrometers or integrated in hybrid systems. Linear ion traps are also ideal platforms for developing and testing new techniques for manipulating gas phase ions in RF trapping fields. Here, a new segmented Linear Quadrupole Ion Trap (LQIT) configuration driven by rectangular RF waveforms is described and basic features of the design offering enhanced performance and extended versatility are highlighted. Methods for sequential manipulation of ions in multiple trapping regions afforded by fast switching of DC electrical potentials for high level control of ion potential energy and transfer between segments are presented.
