Abstract
Effects of atmosphere-pressure, and electrode polarity on the behaviour of spectra excited by a low voltage impulse discharge were investigated using a time-resolved technique. The spectral lifetimes of elements excited to higher states, for example Al III, Ar II, N II, etc., were longer under reduced atmosphere pressures. For the discharge under reduced pressures or when the metal sample was the anode, “spark-like” spectra appeared. For spectrum lines with lower excitation potentials, the effect of atmosphere-pressure was greater than that of polarity. Considering these characteristics, the application of the discharge to the determination of oxygen in iron was recommended.
