Аннотация
Mass peaks are calculated using the numerical simulation of ion trajectories in the linear quadrupole with the dipole excitation(s). Using this data, diagrams for transmission versus resolution are calculated both for the ideal quadrupole field and for the quadrupole field with round rods. It is shown that, using the dipole excitation mode, resolution may be increased from R0.1 = 1000 to R0.1 = 2200 with 20% QMF transmission in an ideal case, and, for the round rods, the dipole excitation along the isoline βy = 0.01 enables an increase in resolution R0.1 from 500 to 800 at a 20% level of transmission.
