Keywords:arc plasma wind tunnel, isotope analysis

As a uniform and rapid isotope analysis method which is not dependent from sample style or contained elements, we present novel method which atomize sample in upper section of arc plasma wind tunnel nozzle and get narrow atomic spectra in arc-jet flow after expansion at nozzle. In this experiment, we examined conditions of steady atomization of strontium by observing emission spectra, when SrCl₂ powder is mixed with Ar arc-jet operating gas.
