Abstract
The instrumentation, initial observations, and operating characteristics ofa pulsed radio-frequency glow discharge atomic emission source are described. Anomalies In the temporal emission intensity wave forms for some analyze transitions are a b reported. These anomalies take the form of a well defined intensity maximum located either near the beginning of the discharge pulse or just after power termination,depending on the particular transition. Still other analyze transitions demonstrate no such temporal irregularities.Selective, gated, detection of these emission anomalies suggests possible analytical advantages in terms of instantaneous emission intensities, which may translate into improved analytical sensitivities.Keywords
