A simple and precise determination method for platinum group elements (PGEs) and Re in rock samples was developed using isotope dilution coupled with inductively coupled plasma mass spectrometry (ID-ICP-MS). Cation exchange separation was employed for simplicity, because it is applicable to group separation and simultaneous isotopic measurement in contrast with the widely used anion exchange separation...
An inductively coupled plasma mass spectrometry (ICP-MS) procedure for determining trace amounts of rare earth elements (REEs), Th and U in chondritic meteorites (chondrites) is presented. As chondrites have low contents of these elements (10 -2 to 10 -4 crustal rock averages), the procedure was designed to be performed in as small a scale as possible in order to reduce...
