Atmospheric-pressure dielectric-barrier discharge as a radiation source for optical emission spectrometry

Abstract

Honey, I shrunk the spectrometer: The use of atmospheric-pressure dielectric-barrier discharge (DBD) as a radiation source for atomic optical emission spectrometry (OES) allowed the construction of a miniaturized DBD-OES system. A microsequential injection configuration (the picture shows the DBD unit and its cross-sectional configuration, HV=discharge power) provides favorable analytical performance for the system, as demonstrated for the determination of mercury.
