Characterization of zirconium alloy by glow discharge optical emission spectrometer

The present paper discusses about a new method developed for determination alloying elements as well as impurities in Zirconium alloy using Glow Discharge Optical Emission Spectrometer (GD-OES). The method was validated with the help of available CRMs and other techniques like AAS and ICP-AES. Statistical studies like F-test, Z-test have been carried out and it is observed that the developed method is very accurate and there is no bias in the precision between GD-OES and AAS with respect to alloying elements and between GD-OES and ICP-AES with respect to impurity elements in Zircaloys.
