Abstract
An ion transfer device for transferring ions from one chamber to another, reduced-pressure chamber includes an inlet section and a main capillary section. The inlet section has a lumen and the main capillary section has a bore communicating with the lumen. The inside diameter of the lumen is less than that of the bore. The inlet section may be removable from an installation site separately from the main capillary section. The ion transfer device may be utilized, for example, in an atmospheric-pressure interface of a mass spectrometer.
