title: A tandem time-of-flight mass spectrometer: combination of a multi-turn time-of-flight and a quadratic-field mirror.
abstract: A tandem time-of-flight (ToF) mass spectrometer consisting of a multi-turn time-of-flight (ToF) and a quadratic-field ion mirror has been designed and constructed. The instrument combines the unique capabilities of both ToF instruments, namely high-resolution and monoisotopic precursor ion selection from the multi-turn ToF and temporal focus for fragment ions with different kinetic energies from the quadratic-field mirror. The first tandem mass spectra for this unique combination of ToF systems are presented.
