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 CAPABLE OF MEASURING IONS WITH LARGER MASS COMPARISON WITH THE CASE OF USING EXISTING RF AMPLIFIER

摘要

PURPOSE: A Fourier transform ion cyclotron resonance mass spectrometer using ultra-wideband RF amplifier and a method for improving signal of Fourier transform ion cyclotron resonance mass spectrometer are provided to add DC offset to high voltage signal by using wide operation frequency range.;CONSTITUTION: A Fourier transform ion cyclotron resonance mass spectrometer comprises a signal generating unit(10), a voltage amplifier(20), a ion cyclotron trap(30). The signal generating unit generates a sine wave shaped first voltage signal having DC offset. The voltage amplifier receives the first voltage signal from the signal generating unit, and generates a second voltage signal. The ion cyclotron trap receives the second voltage signal, and generates ion cyclotron action around the location determined by the DC offset.;COPYRIGHT KIPO 2012
