Characterisation of Dielectric Barrier Discharges for analytical applications — •Joachim Franzke, Alexander Schütz, Sebastian Brandt, David Klute, Sebastian Burhenn, and Pascal Vogel — ISAS - Leibniz-Institut für Analytische Wissenschaften - ISAS - e.V., Bunsen-Kirchhoff-Str. 11, 44139 Dortmund, Germany

Two decades ago the potential of dielectric barrier discharge plasma was presented for use in analytical element spectrometry [1]. It was a miniature planar DBD, characterized by small size, low power consumption, low gas temperature and excellent dissociation capability for molecular species. Several years later a capillary shaped DBD was presented by Na et al. [2] applied as an efficient method for molecular mass spectrometry resulting in the development of a variety of methods now commonly termed Ambient Mass Spectrometry (AMS), which experienced a very rapid development during the last years. Here themes will be presented and tried to be characterized where dielectric barriers were used in the field of Analytical Chemistry like diode laser spectrometry at low pressure DBDs [1], DBD as soft ionization source at ambient air[3,4].
