ABSTRACT:
The present invention relates to an ion trap with a large trap capacity. A mass spectrometer comprises a first linear ion trap that performs mass selective ejection, and a second linear ion trap that accumulates and then mass selectively ejects ions ejected from the first linear ion trap. Directions of resonant excitation of ions of the first linear ion trap and of the second linear ion trap are orthogonal. Compared to conventional art, sensitivity is significantly improved.
