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.
