Estimating the term…
A jet disturber used in combination with an ion funnel to focus ions and other charged particles generated at or near atmospheric pressure into a relatively low pressure region, which allows increased conductance of the ions and other charged particles. The jet disturber is positioned within an ion funnel and may be interfaced with a multi-capillary inlet juxtaposed between an ion source and the interior of an instrument maintained at near atmospheric pressure. The invention finds particular advantages when deployed to improve the ion transmission between an electrospray ionization source and the first vacuum stage of a mass spectrometer.
A method for introducing charged particles into a device comprising the steps of:
An apparatus for introducing charged particles generated at a relatively high pressure into a device maintained at a relatively low pressure comprising an ion funnel having a jet disturber positioned within said ion funnel.
