Abstract

Abstract: To build up the determination of bezoar detoxification in the uncertainty degree by HPLC-ICP-MS（high performance liquid chromatography-inductively coupled plasma mass spectrometry technology）. According to JJF 1059.1-2012 ‘Evaluation and Expression of Uncertainty Measurement’, the uncertainty degree of HPLC-ICP-MS result of arsenic speciation in bezoar detoxification was analyzed. The results showed that the main effect factors of measurement uncertainty include uncertainty degree of standard solution density, uncertainty degree of work curve equation and that of sample repeated measuration. Components of uncertainty and the combined uncertainty were deduced and calculated. We can obtain the evaluation of uncertainty of arsenic speciation in bezoar detoxification by HPLC-ICP-MS.

Key words: HPLC-ICP-MS, detection uncertainty, bezoar detoxification, arsenic speciation
