Abstract:

Mass spectroscopy (MS) was used for detection of oxygen and nitrogen species produced by negative polarity
high pressure glow discharge (HPGD). Atomic O and N species as well as nitrogen oxides NO and NO 2 were
detected. It was not possible to detect ions generated in the discharge directly. As shown by chemical kinetic
model, concentration of negative ions is negligible in HPGD because of elevated temperature. Chemical kinetic
model was also used to study formation pathways of species detected by MS.
