摘要
A Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS) includes: an ionization source generating ions; a deceleration lens, on which the ions generated by the ionization source and spatially dispersed are incident, selectively decelerating the incident ions so as to decrease the distance between the ions; and an ion cyclotron resonance cell on which the ions passing through the deceleration lens are incident. By preventing dispersing of ions due to mass difference and converging the ions using the deceleration lens, the mass range that can be measured at one time can be extended. Also, measurement sensitivity can be improved since the ions are effectively introduced to the ICR cell.
