Estimating the term…
A multi-capillary inlet to focus ions and other charged particles generated at or near atmospheric pressure into a relatively low pressure region, which allows increased conductance of ions and other charged particles. The multi-capillary inlet is juxtaposed between an ion source and the interior of an instrument maintained at near atmospheric pressure, it finds particular advantages when deployed to improve the ion transmission between an electrospray ionization source and the first vacuum stage of a mass spectrometer, and finds its greatest advantages when deployed in conjunction with an electrodynamic (RF) ion funnel deployed within the interior of the mass spectrometer, particularly an ion funnel equipped with a jet disturber.
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 region into a device whose interior is maintained at a relatively low pressure region comprising a plurality of apertures extending into the device and an ion funnel to receive ions at the interior of the device and adjacent to the plurality of apertures, whereby charged particles generated in the relatively high pressure region move first through the plurality of apertures and then through the ion funnel.
