New possibilities of atomic emission spectrometry for the determination of elements with high excitation energies

Analytical characteristics of a high-temperature arc plasmatron with helium gas possessing high heat conductivity and high ionization potential as a plasma-forming gas have been investigated. A system of multichannel photoelectronic registration of spectra have been used in the scheme of a spectral instrument for atomic emission spectrochemical analysis. Based on the results obtained on examples of fluorine and chlorine, a procedure was proposed for the atomic emission spectrochemical determination of heavy excitable elements in powder samples.
