GB/T 16484.3-2009 《Chemical analysis methods of rare earth chloride and light rare earth carbonate - Part 3: Determination of fifteen REO relative contents - Inductively coupled plasma atomic emission spectrometry》 Related products

GB/T 16484.3-2009 standard specifies the determination method of 15 rare earth element oxides in rare earth chloride and carbonic acid light rare earth. Inductance coupled plasma emission Light spectrum method (ICP-OES) was used to dissolve the sample by muriatic acid, and the light spectrum excitation measurement was carried out with argon plasma Light source in dilute muriatic acid medium. Spectral interference between elements was corrected by coefficient correction method to ensure the accuracy of measurement. The standard is suitable for quantitative analysis of 15 rare earth element oxides and provides a stable and accurate determination technology.
