Abstract
A method for analyzing a sample comprising the steps of: generating ions from the sample within an ionization chamber at substantially atmospheric pressure; entraining the ions in a background gas; transferring the background gas and entrained ions to an evacuated chamber of a mass spectrometer system using a single-piece capillary having an inlet end and an outlet end, wherein a portion of the capillary adjacent to the outlet end comprises an inner diameter that is greater than an inner diameter of an adjoining portion of the capillary; and analyzing the ions using a mass analyzer of the mass spectrometer system.
