Abstract

An electrospray ionization device includes a sample conduit providing a sample flow path in a sample flow direction; a first gas conduit surrounding the sample conduit and having an annular outlet; a support structure surrounding the sample conduit; a housing surrounding the sample conduit and includes a first end at the support structure and an axially opposite open second end; and a second gas conduit. The first gas conduit provides a first gas flow path in the sample flow direction. The second gas conduit has a second gas inlet and a second gas outlet in open communication with the housing and provides a second gas flow path from the second gas outlet into the housing that is in the sample flow direction, surrounds the sample conduit and is constrained in a radial direction by the housing.
