Abstract
In discharge‐flow systems employing electron paramagnetic resonance detection, intense spectrometer noise is present under certain conditions. This noise is due to free electrons produced in the discharge and can be eliminated by the addition of an electron scavenger to the flow. Using SF6 to suppress the noise, EPR spectroscopy can be used to identify and study transient species within a millisecond after their formation in an electrical discharge.Keywords
