Journal of Applied Spectroscopy Aims and scope

Abstract

Methods for the introduction of nonconducting powder samples containing halogens into the corona of a low-voltage pulsed discharge in a vacuum are considered. It is shown that the spectra of the halogens can be obtained by using double layer pellets. Using the resonance lines in the spark spectra of bromine and iodine in the analysis enabled one to determine contents of down to 0.5 microgram which in combination with a preliminary enrichment corresponds to a relative sensitivity of 5 · 10−5%.
