The GB/T 16484.2-2009 standard specifies a method for determining the oxidation europium content in rare earth chloride and carbonic acid light rare earth. The method uses Inductance Coupled Plasma Mass Spectrometry (ICP-MS) to analyze the sample in dilute acid medium by dissolving it with nitric acid. Internal standafard method is used for calibration with argon plasma as the ionization source to ensure the accuracy of the determination. The range suitable for determination of oxidation europium is 0.010%~ 0.50%. The standard provides standardized determination techniques for rare earth chemical analysis, ensuring the Reliability of analytical results.
