The general principles of quadrupole
mass analyzer modeling using the ion optics simulation software SIMION 7 3D
were analyzed. A model of quadrupole mass analyzer with circular electrodes
was developed. The shape of the mass peak was calculated. The influence of
the mass analyzer operating mode and length on transmission was investigated.
The data obtained were compared with analytical theory and data of numerical
calculations. Good agreement was observed.
