Abstract
A quadruple focusing time of flight mass spectrometer is disclosed comprised of a deflection zone including four separate focusing electrode pairs for each sequentially guiding ions through a deflection arc with limited divergence from a central reference plane. The focusing electrode pairs are arranged so that ions exit from the deflection zone in a direction opposite to that of their direction of entrance.
