A planar quadrupole device for transmitting and trapping ions in high vacuum.

ABSTRACT:

Rationale

Hybrid mass spectrometers combine multiple mass analyzers to achieve optimal performance in terms of tandem mass spectrometry, high mass resolving power, and mass measurement accuracy for studying highly complex samples. As a result, the need for transport, trapping, and control of ion kinetic energies is critical for the successful integration of multiple mass analyzers and hybrid instrument operation. In addition, transportation of ion populations between two physically distinct locations can result in time-of-flight (TOF) discrimination against ions with widely disparate m/z values, compromising full mass spectral performance. In this work, we demonstrated a new ion guide, referred to as a planar quadrupole (PQ) ion guide, composed of two parallel printed circuit board
