| Abstract: | A method for the direct determination of ultra-trace rare earth elements (REE) in seven Chinese chondritic meteorites by inductively coupled plasma mass spectrometry (ICP-MS) was developed. Samples were digested with a mixture of HF+HNO3 acids in Teflon pressure bomb. The accuracy and precision of the method were assessed by the analysis of four standard reference materials including one chondrite (Allende) and three basalts (BCR-1, BHVO-1 and W-2), the results obtained in this study agree quite well with the recommended values. The reproducibilities (expressed as RSD) of samples were less than 5%. |
