Реферат:	eng: Conditions for atomic emission analysis using a Grand spectrometer equipped with a double-jet arc plasmatron as the excitation source are optimized. The impact of the plasma-forming and carrier gas flow rate on the analytic signal of precious metals is studied. On the basis of the mathematical method of multifactor experimental design, the influence of various factors on the intensity of the spectral lines of analytes are ascertained, and optimally compromise conditions for the determination of noble metals are chosen. An evaluation of the analytical capabilities of the Grand spectrometer is performed, and the detection limits for precious metals (PM) under chosen optimum conditions are calculated. © 2016, Pleiades Publishing, Ltd.
