Abstract:
The analysis of aluminium and its alloys has been studied with use of five standards from Johnson Matthey and ten aluminium alloys from Aluminium Pechiney. The relative sensitivity coefficients for Mg, Al, Si, Ti, Cr, Mn, Ni, Cu, Zn, Sn and Pb were determined vs. iron as an internal standard. They were obtained, by using electrical detection, with a mean precision of 10% relative standard deviation. The sensitivity coefficients measured appear to be independent of the elemental concentration, but for some elements, especially the more volatile ones, remarkable changes were noticed when sparking conditions were altered and when the electrode temperature was changed by cooling with liquid nitrogen.
