近年来，介质阻挡放电（DBD）分析应用得到了快速发展。DBD设计和参数以及它们所用于的应用可以有很大的不同。这导致了一个多样化的领域，有许多明显独特的系统，都基于相同的物理原理。在用于化学分析的DBD中，最显著的变化是放电电极如何与点燃的放电气体分离。虽然DBD的官方定义指出至少一个电极必须被电介质覆盖才被认为是DBD，但是也可以实现两个电极都被电介质层覆盖的配置。电极表面在多个等离子体相关技术领域（例如表面处理或溅射工艺）中起着重要作用，因此已被非常详细地研究。分析DBD通常在低功率和大气压下操作，使得从上述研究领域获得的见解和技术的直接转移变得复杂。本文主要比较了低温等离子体探针（LTP）和介质阻挡放电软电离（DBDI）两种DBD结构。LTP代表具有一个覆盖电极的DBD和两个电极都被覆盖的设计的DBDI。这两种配置非常适合系统比较，因为它们基于介电毛细管的相似几何设计。
Dielectric barrier discharge (DBD)-based analytical applications have experienced rapid development in recent years. DBD designs and parameters and the application they are used for can vary considerably. This leads to a diverse field with many apparently unique systems that are all based on the same physical principle. The most significant changes among DBDs used for chemical analysis are in how the discharge electrodes are separated from the ignited discharge gas. While the official definition of a DBD states that at least one electrode has to be covered by a dielectric to be considered a DBD, configurations with both electrodes covered by dielectric layers can also be realized. The electrode surface plays a major role in several plasma-related technical fields, surface treatment or sputtering processes, for example, and has hence been studied in great detail. Analytical DBDs are often operated at low power and atmospheric pressure, making a direct transfer of insight and know-how gained from the aforementioned well-studied fields complicated. This work focuses on comparing two DBD configurations: the low temperature plasma probe (LTP) and the dielectric barrier discharge for soft ionization (DBDI). The LTP is representative of a DBD with one covered electrode and the DBDI of a design in which both electrodes are covered. These two configurations are well suited for a systematic comparison due to their similar geometric designs based on a dielectric capillary.
