Packets of ions ,—I are introduced into a device. A first electric field is applied for dispersing the ion packets temporally or spatially according to their 0 mobilities A second intermittent traveling wave is applied for regrouping or merging the dispersed ion packets into a lesser number \" of trapping regions with narrower peaks. The ions packets are compressed into the narrower peak regions by varying a duty cycle of C: the intermittent traveling wave.
