Abstract
A mass spectrometer is disclosed comprising an electric field region L2 wherein a time-varying electric field is applied thereto. In a mode of operation a pulse of ions 3 comprising ions having different mass to charge ratios passes through the electric field region L2 and the electric field is varied with time such that at least some of the ions 3 having different mass to charge ratios subsequently arrive at the extraction or acceleration region 10 of a Time of Flight mass analyser at substantially the same time.
