Dielectric barrier discharge devices

2022
The use of dielectric barrier discharge (DBD) plasmas for gas phase dissociation of analyte molecules, after vapor generation and prior to spectrometric detection, is discussed. Their performance in terms of sensitivity, detection limit, resistance to interferences, etc. is evaluated and compared to atomizers/excitation sources routinely used in atomic

Characteristics of Dielectric Barrier Discharge

AIP Conference Proceedings, 2007
The most efficient method to get cold plasma at atmospheric pressure is dielectric barrier discharge(DBD). By this method, which has application area at industry, non‐equilibrium plasma conditions can be generated. In DBD’s, short‐lived large numbers of electrical breakdowns called microdischarges are significant.

Dielectric barrier discharges in analytical chemistry

The Analyst, 2011
The present review reflects the importance of dielectric barrier discharges in analytical chemistry. Special about this discharge is-and in contrast to usual discharges with direct current-that the plasma is separated from one or two electrodes by a dielectric barrier.

Development of dielectric-barrier-discharge ionization

Analytical and Bioanalytical Chemistry, 2014
Dielectric-barrier-discharge ionization is an ambient-ionization technique. Since its first description in 2007, it has attracted much attention in such fields as biological analysis, food safety, mass-spectrometry imaging, forensic identification, and reaction monitoring for its advantages, e.g., low energy consumption, solvent-free method, and easy ...

Liquid analysis dielectric capillary barrier discharge

Analytical and Bioanalytical Chemistry, 2010
In this study a simple micro-tube-based system for analysis of metal-containing liquids is introduced and its analytical performance is evaluated. It is based on a miniaturised dielectric barrier discharge driven at atmospheric pressure. The emission lines of various elements are observed.

Research on Electrical Characteristics of Dielectric Barrier Discharge and Dielectric Barrier Corona Discharge

Japanese Journal of Applied Physics, 2012
The dielectric barrier corona discharge (DBCD) in a wire-cylinder configuration and the dielectric barrier discharge (DBD) in a coaxial cylinder configuration are studied. The discharge current in DBD has higher pulse amplitude than in DBCD. The dissipated power and the gas gap voltage are calculated by analyzing the measured Lissajous figure. DBCD has

Compact dielectric barrier discharge excilamps

Physica Scripta, 2010
In this work, we studied the energy, time, spatial and spectral characteristics of compact KrCl-, XeCl-, XeBr- and Xe2-excilamps of various designs. The maximum radiation power density was ~30 mW cm−2 at an efficiency of 2.5%. It is shown that under optimum conditions in terms of UV efficiency, the discharges for all excilamp designs have a diffuse ...

Dielectric barrier discharge plasma reactor

High Energy Chemistry, 2016
A dielectric barrier discharge plasma reactor has been designed and constructed. The space discharge regime has been implemented. The reactor operating conditions for the desired reaction have been calculated using the dissociation of water molecules as a model reaction.

Dynamics of dielectric micropore discharge in atmospheric pulsed dielectric barrier discharge

Physics of Plasmas, 2023
In this paper, a two-dimensional self-consistent fluid model was developed in atmospheric helium for dielectric barrier discharge excited by microsecond voltage pulses, in which a dielectric sheet with micropore is inserted in the interelectrode gap.
