Abstract

Computer simulation studies were made to analyse the behavior of ionsunder broadband excitation In a cylindrical FTICR ion trap. The mechanism of off-resonance excitation of ions was investigated by displaying the tangential components of the Lorentz force and phase diagram. Itwas found that a combination of the off-resonance effect with the inhomogeneity of an RF excitation field causes incidental z-ejection of trapped ions. (C) 1997 by John Whey & Sons, Ltd.
