An Ion Funnel Interface for Improved Ion Focusing and Sensitivity Using Electrospray Ionization Mass Spectometry

Abstract

This paper describes the ion funnel design and presents an evaluation of its performance using a triple-quadrupole mass spectrometer. Results suggest that it will be feasible to realize close to 100% ion transmission efficiency for analytically relevant ions through the electrospray ionization interface and into the mass analyzer
