1 Scope

This standard specifies the inductively coupled plasma mass spectrometry (ICP-MS) method Yanshi method for the determination of rare earth elements. This standard applies to Yanshitai rare earth elements scandium (Sc), yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), Gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu) measurement. The standard methods of each rare earth element detection limit (mg/kg) were. Sc is 0.05; Y, La, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu were 0.005; Ce is 0.1; Nd 0.025.
