Abstract
Analytical instruments comprise an RF generator, first and second transformers having respective primary and secondary windings, and first and second ion optical devices. The secondary winding of the first transformer and the first ion optical device form a primary LC circuit with a first resonant frequency corresponding to a first frequency generated by the RF generator. The secondary winding of the second transformer and the second ion optical device form a secondary LC circuit with a second resonant frequency. At least part of the secondary LC circuit has a variable inductance that varies based on an output of a phase difference detector such that the second resonant frequency varies in dependence on a magnitude of an output of the phase difference detector.
