Abstract

Objective To establish the method for direct determination of 20 elements in blood by octopole reaction system inductively coupled plasma mass spectrometry (ORS-ICP-MS). Methods The samples were diluted by 0.1% Triton X -100 +0.1% HNO3. The solution was directly analyzed by ORS -ICP -MS for determination of twenty elements, inclduign Pb,As,V,Cd etc. Results The detection limits of each element was between 0.005μg/L～1.09μg/L. Standard linear correlation r≥0.999. Standard deviations were below 5%,recovery rates were in the range of 85.3%～112% .Standard reference materials were used as quality control standards and the analysis results conformed well to the certified values. Conclusion The method is simple,rapid,accurate and reliable for determination of samples.
