Application Note: Elemental Analysis of Residual Oil by EDXRF
10 April 2013

The NEX QC offers analysts a simple yet powerful and versatile system for quantifying elemental composition using the empirical approach. The results of this study indicate that given stable samples, proper sample handling and proper calibration technique, the Rigaku NEX QC EDXRF can achieve excellent results in monitoring the concentration of sulfur, nickel, vanadium and iron in residual oil.
