Simultaneous graphite furnace at. absorption spectrometry was used for trace element detns. in different materials. The comprised settings for exptl. parameters, esp. the heating program were optimized using multicomponent anal. Atomization efficiency was not found to change for elements with atomization temps. for single element detection up to 1000 Deg (Cd and Mo). The sensitivity did not change in the case of simultaneous multielement detn. High purity MgO was analyzed and the found trace element amts., quant., are in good agreement with certified values detd.
