This paper introduces the verification of tin content analysis methods by inductively coupled plasma mass spectrometry(ICP-MS)and graphite furnace atomic absorption spectrometry(GFAAS).The verification contents include detection limit,quantitation limit,repeatability,accuracy(recovery rate)and intermediate precision.The verification data show that the obtained test results are in line with the regulations and meet the acceptable standards of verification,which proves that the two methods are suitable for the inspection of tin elements in this product,and can ensure the accuracy and reliability of the inspection.The two methods were compared and analyzed to detect tin content in disposable infusion pipeline with good reproducibility.
