| Abstract: | The spectra of some volatile hydride forming elements have
been investigated to select thermometric species for determination of excitation temperature in analytical plasmas working in argon under atmospheric
pressure. Groups of lines of
As I, Sb I and Sn I in addition to Ar I were found
appropriate for the determination of excitation temperature in inductively
coupled plasma (ICP) and wall-stabilized arc (WSA). The Boltzmann plots were
straight lines, which determined temperature in ICP and WSA using different
groups of spectral lines that agree well with each other as well with the most
familiarly used thermometric species. These lines are recommended for
determination of temperature when gaseous hydrides are introduced into the
plasma and no other thermometric species except the atoms of working gas are
present. |
