介质阻挡放电(DBD)是科学和工业应用的成熟和有用的工具。由于DBD可以产生小的、低温/功率的大气等离子体，它们在分析应用中引起了极大的兴趣。这类等离子体可通过几种方式用于分析物的检测和定量：DBDS可用作例如通过光发射光谱(OES)检测元素的碎裂和激发源，或用作通过质谱学(MS)检测的分子电离源。ISAS已经开发了几种这种排放物，并研究了DBD本身对随后应用的影响。本文概述了从半导体激光原子吸收光谱分析中的低压DBD到大气DBD的发展，这些DBD可用于不同环境下的应用，如通过OES对砷形态的痕量检测或通过MS对分子化合物进行软电离。
Dielectric barrier discharges (DBDs) are well-established and useful tools for scientific as well as industrial applications. They have been of high interest for analytical applications due to the fact that DBDs can produce small, low temperature/power, and atmospheric plasmas. These kind of plasmas can be applied for the detection and quantification of analytes in several ways: either, DBDs can be used for example as fragmentation and excitation sources to detect elements via optical emission spectrometry (OES), or as ionization sources of molecules for the detection via mass spectrometry (MS). ISAS has developed several of these discharges and studied the impact of the DBD itself on the subsequent application. This work summarizes the development from low pressure DBD implemented in diode laser atomic absorption spectrometry to atmospheric DBDs that can be used for different ambient applications such as the trace detection of arsenic species via OES or the soft ionization of molecular compounds via MS.
