 note = {Rb, Sr and REE (Rare Earth Elements) from rock and mineral powder and natural water were separated by ion-exchange resin with hydrochloric acid (first column separation) as eluent. Sm and Nd were then separated using α-hydroxy isobutyric acid (HIBA) adjusted to pH = 4.5 (second column separation) from that REE fraction. Blanks of Rb, Sr, Sm and Nd in HCl were 0.006 ppb, 0.002 ppb, 0.001 ppb and 0.004 ppb, respectively but those for refined water (used) were 0.002 ppb, 0.0004 ppb, 0.001 ppb and 0.003 ppb. Blanks for Rb, Sr, Sm and Nd during whole procedure were 0.03-0.54 ng, 0.11-0.91 ng, 0.03-0.07 ng and 0.21-0.39 ng.},
