The features of quadrupole mass filter operation in upper and lower vertices of stability quadrangle are studied under pulsed power supply and in the presence of higher-order components in potential distribution. The aim of this work is to compare the influence of various higher-order components on the analytical characteristics of a quadrupole mass filter when operating at upper and lower vertices of stability quadrangle using pulsed power. Using numerical modeling methods, a comparison was made of the operating features of the quadrupole mass filter both in the absence and in the presence of higher-order components in the potential distribution. The research shows that with increasing resolution, the ratio of the intensities of mass peaks increases when working at lower and upper vertices, respectively. Also, if there are certain higher-order components in potential distribution associated with symmetrical distortions of electrode system, the resolution of mass filter increases, both at upper and lower vertices of stability quadrangle.
Key words: : quadrupole mass filter, stability quadrangle, higher order components, mass peak, resolution, mass peak intensity.
