Determination of Trace Elements in Environmental Soil Standard Reference Material with ID-SSMS

An isotope dilution spark source mass spectrometric method (ID-SSMS)for quantitative determination of Cu, Sr, Mo, Ba, Pb, U, Ce, Nd and Ybnine trace elements in environmental soil standard reference material hasbeen developed. The ID-SSMS provides absolute analyses for trace elementswitkout the need of standard reference material. It is mainly used for pre-paring standard refernece materiald. The relative standard deviation is ±4-16%.
