The application of NORDTEST uncertainty evaluation to the determination of ten major and minor components in rocks by X-ray fluorescence spectrometry with fusion sample preparation
The application of NORDTEST uncertainty evaluation to the determination results of 10 major and minor components(including Na2 O,MgO,Al2 O3,SiO2,P2 O5,K2 O,CaO,TiO2,MnO and Fe2 O3) in rock samples by X-ray fluorescence spectrometry with fusion sample preparation was reported.According to the NORDTEST rules,the uncertainty of the determination results of 10 components in 3 national Grade One certified reference materials,namely,GBW07104,GBW07105and GBW07106,was assessed.It was found that the concentration of...
