Abstract
The invention relates to a double focusing mass spectrometer with a combination of an electric and of a magnetic field for directional and velocity focusing. In order to provide a compact and constructionally simple arrangement, it is proposed that a common magnet is used for the Wien filter (10) and the sector magnet (11). Preferably, this double focusing mass spectrometer is used in an MS/MS arrangement.
