This study considers the coupling effect between the cathode and anode regions-the two most important regions in a glow discharge. Cathode and anode processes are tightly coupled by electron and ion coupling effects. Both electron and ion coupling ef

This study maps the complex relationships between the oscillating frequency (210-800 kHz), amplitude (to 4 V p-p), and current 0.18-0.7 mA) for an oscillating-plasma glow discharge GC detector as a function of pressure (0.33-0.83 Torr), electrode spa
