Abstract

See full text

An apparatus for ionizing analyte molecules comprised in a flow of a first gas. The apparatus includes an inlet tube through which the first gas may be discharged into an ionization region. The apparatus also includes a nozzle electrode disposed around the inlet tube to define a substantially annular space between the exterior of the inlet tube and the interior of the nozzle electrode. The sheath tube includes an inlet for introducing a fluid into the substantially annular space and an outlet through which the fluid may be discharged into the ionization region. The apparatus is configured to ionize the analyte molecules optionally via electrospray or chemical ionization.
