Objective

To establish an analytical method for the simultaneous determination of 19 kinds of metal elements in Oviductus ranae by inductively coupled plasma mass spectrometry (ICP-MS).

Methods

Samples were digested using a microwave-assisted digestion system with a HNO3-H2O2 (5:2, V:V) mixed acid system. Spectral interferences were eliminated using an eight-stage rod collision/reaction cell system, and instrument parameters were optimized to improve sensitivity and accuracy. Quantification was performed using the internal standard method.

Results

Method validation using certified reference material (GSB-28) and spiked recovery tests showed that the recoveries for the 19 kinds of elements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Sr, Ag, Cd, Cs, Ba, Tl, Pb, U) ranged from 87.8% to 108.6%, with relative standard deviations less than 10%. The limits of detection ranged from 0.1 to 48.3 μg/kg. Analysis of actual samples indicated higher content of elements such as Fe, Mn, Cu, Zn and Sr, while levels of Cr, As and Cd were relatively low.

Conclusion

The established method is simple in sample preparation, highly sensitive and exhibits good stability. It is suitable for the rapid and simultaneous detection of multiple trace elements in Oviductus ranae, providing technical support for quality control and standard formulation.
