Linked scan at constant B/E

This can be performed with a sector instrument incorporating at least one magnetic sector and one electric sector. The magnetic sector field strength, B, and the electric sector field strength, E, are scanned simultaneously, while holding the accelerating voltage, V, constant, so as to maintain the ratio B/E constant. This constant value is determined by the ratio of the two field strengths required to transmit main-beam ions of predetermined mass/charge ratio. These preselected main-beam ions are the precursor ions whose fragment ion spectrum is required. The term B/E linked scan is not recommended.
