Abstract

Rare earth element (REE) determinations with high accuracy and precision were performed on four geological standard rocks (JA-1, JB-1, -2 and -3) by inductively coupled plasma-mass spectrometry (ICP-MS). In order to achieve this, internal standardization, matrix matching or separation of REE from the matrix elements are recommended. In these analyses, REE data obtained by ICP-MS show excellent agreement (within 5%) with those obtained by isotope dilution method using thermal ionization mass spectrometer. Among these analytical methods of ICP-MS, the most reliable data can be obtained by analysis using a sample solution free from matrix elements.
