Jet flow of vapors in an electric arc and its uses in spectral analysis (a survey)

The effect of the migratory motion of atoms on line intensity in dc arc spectra is considered. Increase in the jet character of vapor flow are accompanied by increases in the fraction of atoms entering the excitation zone. Sensitivity of spectral analysis can be increased by providing for jet flow of iodine vapor through the discharge gap. The use of a carrier (Ga₂O₃) also makes it possible to augment the jet character of the flow at lower vapor flow velocities.
