Abstract:
[Objective] A detection method of indium in human blood was proposed in this paper.

[Methods] Indium was detected through inductively coupled plasma mass spectrometry with optimized instrument tuning parameters. The interference of matrix effect was adjusted through thallium solution (2μg/L).

[Results] The linear range of standard curve was from 0.1μg/L to 100.0 μg/L. The lowest detection limit was 0.5 μg/L and the average recovery rates ranged from 97.7% to 101.9%. The precisions of relative standard deviation (RSD)were all lower than 4.9%.

[Conclusion] The proposed protocol in current study was simple and suitable for fast detection of indium in human blood.
