Abstract:
Objective:To establish a method for the determination of residual 5 heavy metal elements in single use and gravity feed infusion sets and intravenous infusion needles, including Cd, Cr, Cu, Sn and Pb. Methods:After the pre-preparation,the sample was dissolved in 1% nitrate. The 5 heavy metal elements in the sample solution were determined by inductively coupled plasma mass spec-trometry (ICP-MS). Results:Under the ICP-MS assay conditions, each element showed good linearity within the range of 0-50 ng· ml-1(r>0. 999 0). The average recoveries were within the range of 92%-116% and 1. 6%-2. 9%, respectively (RSD<3,n=9). Conclusion:The operation is simple and can meet the demand for the analysis of heavy metal elements in single use and gravity feed infusion sets and intravenous infusion needles.
