Abstract
The present invention relates to a system and method for mass spectrometry () that allows for bi-directional introduction of collections of charged particles into the magnetic field of a mass spectrometer. More particularly, the present invention includes a system for mass spectrometry () (e.g., an FTMS mass spectrometer) with a cylindrical magnet () configured to receive and measure the cyclotron frequencies () of charged particles that are introduced () into the cylindrical magnet () from either of the two axial ends thereof. Methods of the invention relate to performing mass spectrometry analysis on collections of charged particles that are introduced (), serially, simultaneously or both, into a cylindrical magnet () from opposing axial ends thereof. The present invention exhibits significantly increased magnet throughput relative to currently available devices, by allowing flow in the opposite direction to a second detector, e.g., during ion processing time of a first detector.
