While typical ion-counting peak hopping methods using a single Daly detector or a single secondary electron multiplier have proven very effective in analyzing small Pb samples by TIMS, the measurements often require long acquisition times, typically of several hours. Here we compare and evaluate static multi-collector determination of Pb isotope ratios in samples containing between 100 and 1pg total...
Very precise silver (Ag) isotopic compositions have been determined for a number of terrestrial rocks, and high and low Pd/Ag meteorites by utilizing multicollector inductively coupled plasma mass spectrometry (MC-ICPMS). The meteorites include primitive chondrites, the Group IAB iron meteorites Canyon Diablo and Toluca, and the Group IIIAB iron meteorite Grant. Silver isotopic measurements are primarily...
