Abstract

A jet disrupter in a dual channel ion funnel electrospray ionization (ESI)-mass spectrometry (MS) interface design was used to control ion transmission. The electrosprays were aligned with a dual heated capillary and the exits of the capillaries were aligned with a dual channel inlet section of the ion funnel. The two channels converge into a single channel and the ions from both channels were mixed and transmitted together into the mass analyzer. The results show that efficient ion transmission is maintained in the main channel of the ion funnel for a broad range of m/z ions while ion transmission in the jet disrupter is effectively modulated.
