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. This gives rise to two main features of the dielectric barrier discharges; it can serve as dissociation and excitation device and as ionization mechanism, respectively. The article portrays the various application fields for dielectric barrier discharges in analytical chemistry, for example the use for elemental detection with optical spectrometry or as ionization source for mass spectrometry. Besides the introduction of different kinds of dielectric barrier discharges used for analytical chemistry from the literature, a clear and concise classification of dielectric barrier discharges into capacitively coupled discharges is provided followed by an overview about the characteristics of a dielectric barrier discharge concerning discharge properties and the ignition mechanism.
本综述反映了介质阻挡放电在分析化学中的重要性。这种放电的特殊之处在于——与通常的直流放电不同——等离子体通过介电阻挡层与一个或两个电极隔开。这导致了介质阻挡放电的两个主要特点；它可以分别作为解离和激发装置以及电离机制。本文描述了介质阻挡放电在分析化学中的各种应用领域，例如用于元素检测的光学光谱法或作为质谱的电离源。除了从文献中介绍用于分析化学的不同类型的介质阻挡放电外，还提供了一种清晰简洁的分类，将介质阻挡放电分为电容耦合放电，并概述了介质阻挡放电在放电特性和点火机制方面的特点。
