A linked scan at constant B<sup>2</sup>/E may be performed on a [[sector instrument]] that incorporates at least one [[electric sector]] plus one [[magnetic sector]]. It involves holding the [[Accelerating Voltage|accelerating voltage]] fixed and scanning the magnetic field (B) and the electric field (E) simultaneously so as to maintain the ratio B<sup>2</sup>/E at a constant value. This constant value corresponds to the ratio of the two fields which transmit main-beam ions of predetermined mass-to-charge ratio; these pre-selected main-beam ions are the fragment ions whose precursor ion spectrum is required. The fragmentation reactions thus observed occur in a [[FFR|field-free region]] traversed before the two sectors scanned in this way. This term should not be used without prior explanation of the meanings of B and E.
