| Description | ICP-OES is a suitable method for the determination of R.E.E. (rare earth elements), which exhibits advantages in the absence of interferences of evaporation, low detection limits and a great linear range of calibration graphs. A spectrometer having spectral bandwidth (SBW) 30 pm with the 50 MHz ICP source were used. Optimum working conditions resulted from detailed studies of axial intensity distributions. Differences in axial intensity distribution were evident when compared with usual 27.12 MHz ICP sources. Matrix interferences of alkaline salts and acids have been evaluated and the optimum spectral lines selected respecting mutual spectral interferences of R.E.E. |
