ABSTRACT:
A mass analyzer for isolating, fragmenting and scanning ions. The mass analyzer includes an ion trap having a first electrode, a second electrode adjacent to the first electrode, and a third electrode interposed between the first electrode and the second electrode, a first RF source electrically connected to the first electrode and second electrode and a second RF voltage source electrically connected to the third electrode. The second RF voltage source provides for a second electrical field for fragmenting ions and broadens the potential application of the fragmentation cut-off of the device allowing for analysis of peptides and other complex molecules. The mass analyzer may be used independently or in combination with a mass spectrometry system. A method of ion fragmentation and cut-off is also disclosed.
