In this work, the quantities have been determined experimentally that are needed for reliable and precise quantitative interpretation of Auger spectra of nitrides AlN, GaN and of their ternary alloys AlxGa1 - xN. Measurements of reference samples AlN and GaN under various parameters of the primary electron beam (energy 3 and 5 keV, beam incidence angle with respect to the surface normal 12.5° and 45°) and of the ion beam (energy 0.5 and 1.0 keV, beam incidence angle with respect to the surface normal 67.5° and 35°) allowed to find the elemental sensitivity factors for these nitrides, and measurements on reference samples of ternary alloys AlxGa1 - xN allowed to find the component sputtering yields YGa/YAl. To the best of our knowledge there is a lack of such data for those materials in the literature.
