[Objective] To investigate the method of indium in human blood. [Method] The determination of indium in blood by inductively coupled plasma mass spectrometry was optimized. The interference of working parameters and matrix effect was calibrated with 2μg / L thallium solution. [Result] The linear range of standard curve was 0.1-100.0μg / L, the lowest detection concentration was 0.5μg / L and the average recovery was 97.7% -101.9%. The relative standard deviations (RSDs) of the standard curve were less than 4.9% . [Conclusion] The method is simple, rapid and accurate, suitable for the detection of indium in human blood.
