A METHOD AND APPARATUS FOR IMPROVING OF ION CYCLOTRON RESONANCE MASS SPECTROMETER SIGNAL

摘要

PURPOSE: A control device for improving signal capability of an ion cyclotron resonance mass spectrograph is provided to improve signal sensibility by supplying voltage for ion movement and controlling deflection. CONSTITUTION: An excitation electrode control means applies a high frequency signal or a control signal from a high-frequency amplifier(7) to a first excitation electrode and a second excitation electrode. A detection electrode control means applies an arbitrary waveforms generated in first and second control signal generating units(21, 23) to each detection electrode. A detection electrode signal processing signal detects an ion signal from first and second detection electrodes and amplifies and changes the ion signal into a digital signal. An excitation electrode signal processing means detects an ion signal from the first and second excitation electrodes. The excitation electrode signal processing means amplifies and changes the ion signal into the digital signal. A first excitation switching unit(12) selectively outputs by a computer control program.
