ELECTROSPRAY EMITTER DEVICES AND METHODS OF USE THEREOF

Abstract: disclosed herein are electrospray emitter devices for delivering a fluid sample to a mass spectrometer, the emitter devices comprising a sample capillary extending from a sample inlet to a sample outlet said sample capillary defining a path for fluid flow from the sample inlet to the sample outlet. the sample inlet is configured to receive a fluid sample, the fluid sample being an eluent from a liquid chromatograph. a reagent capillary extending from a reagent inlet to a reagent outlet, the reagent capillary defining a path for fluid flow from the reagent inlet to the reagent outlet. a first conduit disposed around a first portion of the sample capillary and a first portion of the reagent capillary; the first conduit comprises a wall defining a lumen, the first conduit extends from a first end to a second end opposite and axially spaced apart from the first end.
