A plasma-mediated vapor generation (PMVG) by a dielectric barrier discharge (DBD) from a single sample drop of inorganic mercury and methylmercury was investigated for subsequent detection by atomic absorption spectrometry (AAS). A volume discharge DBD reactor with a highly flexible laboratory made high voltage power supply were fabricated. The PMVG efficiency was quantified to 87% ± 8% for Hg2+ and 91% ± 10% for MeHg+, respectively.
