Outline
To establish a simultaneous determination method by inductively coupled plasma mass spectrometry（ICP-MS）for 32 elements and 15 rare-earth elements in whole blood including Ni, Sb, Li, Be, Mn, Co, Ge, Cd, Sn, Te, W, Tl, Bi, Ga, Cs, Mo, Cr, U, V, Ba, Sr, As, Al, Ti, Pb, Cu, Se, Rb, Zn, Fe, Ca, Mg, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y.
Blood samples were diluted 20-fold with a 0.05% Triton X-100-0.5% HNO3 and then the analytes were determined by ICP-MS. Sc, Rh, Os, and Ir were selected as internal standards. The helium collision mode（KED）was used to eliminate interferences for some elements.
The 47 elements showed good linearities with correlation coefficients greater than 0.999. The method detection limits were 0.001-1.55 μg/L（Fe, Ca, and Mg were 0.01-0.06 μg/mL）. The within-batch RSDs were less than 10%, and the between-batch RSDs were less than 15%. The average recovery rates ranged from 75.6% to 120.9%. The average determination results of 22 elements in the whole-blood reference material were within the uncertainty range of the certified values.
This method is simple and fast, with high sensitivity, good stability, low detection limits, and it is suitable for the determination of 47 elements in blood samples.
