Abstract:
A lens for electron capture dissociation may include: a first electrode and a second electrode spaced apart from each other and arranged along a first direction; and a third electrode and a fourth electrode spaced apart from each other and arranged along a second direction perpendicular to the first direction. The first electrode and the second electrode may be disposed in a space in which a magnetic field is formed in the first direction and trap electrons. The third electrode and the fourth electrode may be in the form of a flat plate and may apply an electric field to the trapped electrons in the second direction.
Abstract:
A Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) may include: a signal generator generating a sinusoidal, first voltage signal having a DC offset; a voltage amplifier receiving the first voltage signal from the signal generator and generating a second voltage signal by amplifying the first voltage signal; and an ion cyclotron resonance (ICR) trap receiving the second voltage signal and generating an ion cyclotron motion centered on the position determined by the DC offset.
