1. During the glow discharge region, the air becomes a conductor. 2. Glow discharges may also be operated in radio-frequency.3. Both bulk and depth analysis of solids may be performed with glow discharge . 4. Glow discharge is facilitated by electrons striking the gas atoms and ionizing them.5. The requirement for samples of glow discharge atomizers is that they are electrical conductors. 6. Glow discharge radiation, ?-radiation, and ultraviolet irradiation have been used.7. The figure above shows the main regions that may be present in a glow discharge . 8. In analytical chemistry, glow discharges are most often operated in direct-current mode. 9. Excited states are formed in a glow discharge in a chamber through which the gas flows. 10. The majority of industrial plasma processing is conducted with glow discharges at pressures below 10 torr.
