Microsecond pulsed glow discharge applied to a sector-field mass-spectrometer

Abstract

A microsecond pulsed glow discharge (PGD) is applied to an existing commercial sector-field mass spectrometer to develop a system for routine analysis with PGD. The detection limits obtained are of the same order of magnitude as in DC discharge, which is explained by the geometry of the existing discharge cell. Additionally, the dynamics of ions extracted from PGD are measured for further development of pulsed ion detection.
