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.
