除了质谱新技术的发展外，软电离源的研究和发展对分析科学也起着重要的作用。由于介质阻挡放电电离（DBDI）被确定为两个时间上分离的事件，选择性地防止重合的等离子体可以导致提高电离强度。虽然DBDI被称为软电离源，但高压振幅和占空比的调制可以导致优化的电离强度。这对于覆盖不同类型的分析物是有利的。
Besides the progress of new mass spectrometer technologies, the investigation and development of soft ionization sources play an important key role for analytical sciences. Since the dielectric barrier discharge ionization (DBDI) is identified as two temporally separated events, a selective prevention of the coincident plasma can lead to improved ionization strength. Although a DBDI is known as a soft ionization source, a modulation of the high-voltage amplitude and duty cycle can lead to optimized ionization strength. This is an advantage to cover different types of analytes.
