Ionization by atmospheric pressure gas discharge has been employed for a long time in mass spectrometry. Inductively coupled plasma mass spectrometry is an exemplar, and widely used for elemental analysis. The technique has less uptake in organic mass spectrometry. We describe a simple source design that can be readily implemented in most atmospheric pressure ionization (API) systems and compare its performance with that of electrospray ionization (ESI) and atmospheric pressure chemical ionization (APCI).

小分子的辉光流电离质谱。辉光流电离源 ('GlowFlow') 与电喷雾电离和大气压化学电离的比较

大气压气体放电的电离已在质谱分析中使用了很长时间。电感耦合等离子体质谱法就是一个例子，并广泛用于元素分析。该技术在有机质谱中的应用较少。我们描述了一种简单的源设计，可以在大多数大气压电离 (API) 系统中轻松实现，并将其性能与电喷雾电离 (ESI) 和大气压化学电离 (APCI) 的性能进行比较。
