The precision high-speed high-frequency generator of quadrupole mass analyzer

Characteristics of the small-sized precision high-speed high-frequency generator of analytical quadrupole mass analyzer are presented. The necessary parameters of the quadrupole analyzer, and accordingly generator parametres are defined, considering modern requirements presented to quadrupole mass analyzers, making a part of various mass spectrometer devices and complexes and realizing high-speed techniques of the analysis. Such parameters include long-term accuracy of mass maintenance within the ranges of 0.1 а.u; hopping from one top of a peak to another during not more than 20 ms with accuracy of hitting the top of a peak not worse than ±0.1 a.u and prolonged work at the top of the peak with this accuracy not less than 8 hours. Quadrupole mass-analyzer can work in two modes: RF - with a wide mass window and transition during 1 s to the mode DC/RF - divisions of ions in relation of mass to a charge.
