Simultaneous determination of the constituents in Al-Ge-Si alloys by inductively coupled plasma atomic emission spectrometry.
An accurate method for determination of the constituents Ge, Si, In and Mg in Al-Ge-Si based compact alloys and foil materials by ICP atomic emission spectrometry is developed. The material samples were dissolved in nitric acid-hydrofluoric acid. Optimum parameters for the simultaneous measurement of the constituent elements are worked out. To compensate the time determined sensitivity fluctuations the analytical signal was corrected by a special procedure of external standardization.
