《GB/T 30714-2014电感耦合等离子体质谱法测定砚石中的稀土元素》由TC298(全国珠宝玉石标准化技术委员会)归口,主管部门为自然资源部(国土)。
本标准规定了用电感耦合等离子体质谱(ICP-MS)法测定砚石中稀土元素的方法。
本标准适用于砚石中稀土元素钪(Sc)、钇(Y)、镧(La)、铈(Ce)、镨(Pr)、钕(Nd)、钐(Sm)、铕(Eu)、钆(Gd)、铽(Tb)、镝(Dy)、钬(Ho)、铒(Er)、铥(Tm)、镱(Yb)、镥(Lu)的测定。
本标准方法中各稀土元素的检出限(mg/kg)分别为:Sc为0.05;Y、La、Pr、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu均为0.005;Ce为0.1;Nd为0.025。
Scope
This standard specifies the method for the determination of rare earth elements in inkstone 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). The detection limits (mg/kg) of each rare earth element in this standard method are: Sc is 0.05; Y, La, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu are all 0.005; Ce is 0.1; Nd is 0.025.
