In one embodiment, a mass spectrometer includes an RF drive circuit for generating RF signals, a quadrupole mass filter, and a fixed connection assembly for delivering RF signals from the RF drive circuit to the quadrupole mass filter, the fixed connection assembly representing the entire delivery path of RF signals from the RF drive circuit to the quadrupole mass filter. By avoiding flexible components such as a freestanding wires or flexible circuit boards, the need for retuning when parts are removed or disturbed for testing or servicing is reduced, and a modular instrument in which components and connections are standardized and therefore interchangeable is realized.

A temperature-regulated radio frequency management system for use in a mass spectrometer is described. The temperature-regulated radio frequency management system having one or more radio frequency components disposed in a vacuum environment. The temperature-regulated radio frequency management system including a radio frequency detection circuit configured to provide feedback indicative of a radio frequency signal in one or more of the radio frequency components. In addition, the temperature-regulated radio frequency management system includes a temperature regulation circuit disposed in the vacuum environment and configured to reduce temperature-induced variations in the detection circuit.
