The amplitudes of the spatial harmonics of the field are calculated for given
displacements of the electrodes in a quadrupole mass filter relative to their
optimum positions. The cases of radial and angular displacements of the
electrodes, asymmetries in voltage supplied to the electrodes, and nonidentical
rod diameters are considered. These data are required for calculating the actual
shape of th... hiện toàn bộ
