    摘要: An interface for use in a mass spectrometer is disclosed. The interface comprises a first ion funnel comprising a first inlet and a first outlet, and a first axis between the first inlet and the first outlet. The interface further comprises a second ion funnel in tandem with the first ion funnel, the second ion funnel comprising a second inlet and a second outlet, and a second axis between the second inlet and the second outlet. The first axis and the second axis are offset relative to one another. A mass spectrometer comprising the interface and a method are disclosed.
