Atmospheric Sampling Glow Discharge Ionization Source for the Determination of Trace Organic Compounds in Ambient Air
TL;DR: In this article, a new atmospheric sampling ion source, based on the establishment of a glow discharge in ambient air drawn into a region of reduced pressure, is described, which exhibits a very short memory and is extremely sensitive for compounds with high proton affinities.
