Scope

This standard specifies the method for the determination of rare earth elements in tea by inductively coupled plasma mass spectrometry (ICP-MS). This standard applies to rare earth elements scandium (Sc), yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium ( Determination of Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu). When the sampling amount of the sample is 2g, and the constant volume is 25mL, the minimum detection mass concentration (ng/g) of each rare earth element in this standard method is respectively: Sc, 0.9; Y, Ce, Pr, Nd, Sm, Eu, Gd , Tb, Dy, Ho, Er, Tm, Yb, Lu are all 0.1.
