ABSTRACT:
The current invention facilitates the construction of a compact high performance quadrupole mass analyzer which has the operational characteristics of a modern research grade system and the ergonomic and cost structure of a moderate benchtop system. A multipole field device is physically located within the windings of the RF resonant circuit. By combining the space consumed by the RF windings and its housing and the space consumed by the multipole field device and its vacuum housing, the overall size of the resultant mass spectrometer is reduced.
