The calculation of monatomic spectral lines' intensities and composition in plasma out of thermal equilibrium; evaluation of thermal disequilibrium in ICP torches

Résumé

The composition and monatomic spectral line intensities are calculated for several thermal disequilibriums in a plasma composed of water, cupric sulphate and argon. The monatomic excitation temperatures are determined experimentally from three chosen spectral lines of copper (510, 515 and 521 nm) in an ICP torch. By comparing the intensity of the argon spectral lines with that of the copper spectral lines, we evaluate the thermal disequilibrium for various excitation temperatures depending on the power input to the plasma.
