Abstract:
An instrument for separating ions may include an ion source in a first pressure environment at a first pressure and configured to generate ions from a sample, an ion separation instrument, controlled to an instrument pressure that is less than the first pressure, and configured to separate ions as a function of at least one molecular characteristic and an interface, controlled to a second pressure less than the first pressure and greater than the instrument pressure, for transporting the generated ions from the first pressure environment into the ion separation instrument operating at the instrument pressure. The interface may include a sealed ion funnel defining an axial passageway therethrough, and an ion carpet sealed to the first ion funnel. A portion of the axial passageway tapers from a first cross-sectional area to a reduced cross-sectional area such that the tapered axial passageway defining a virtual jet disrupter therein.
