Title:
ION GUIDE FOR MASS SPECTROMETRY
Document Type and Number:
WIPO Patent Application WO/2014/057345
Kind Code:
A3
Abstract:
An ion guide is provided having an enclosure extending longitudinally around a central axis from a proximal inlet end to a distal outlet end. The proximal inlet end receives a plurality of ions entrained in a gas flow through an inlet orifice. A deflection plate is disposed within the enclosure between the proximal and distal ends and deflects at least a portion of the gas flow away from a central direction of the gas flow. A plurality of electrically conductive, elongate elements extend from the proximal end to the distal end within the enclosure and generate an electric field via a combination of RF and DC electric potentials. The electric field deflects the entrained ions away from the central direction of the gas flow proximal to the deflection plate and confines the deflected ions in proximity of the elongated elements as the ions travel downstream.
