FOURIER TRANSFORM ION CYCLOTRON RESONANCE MASS SPECTROMETER USING ULTRA-WIDEBAND RF AMPLIFIER AND METHOD FOR IMPROVING SIGNAL OF FOURIER TRANSFORM ION CYCLOTRON RESONANCE MASS SPECTROMETER

摘要

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.
