The Q-TOF is tandem mass spectrometer coupling a conventional quadrupole front end with an orthogonal time-of-flight (TOF) final stage. It offers electrospray and nanoelectrospray ionization modes. The TOF MS offers exact mass measurement capabilities (3 ppm) for the determination of elemental composition and increased specificity for the identification of unknowns. The high full scan sensitivity is used for comparative metabolomic global profiling where the maximum amount of information is required from a sample.
