Abstract
Determination of 25 trace elements in the meteorites Allende and Murchison by ICP-MS is described. Samples are digested using HF, HNO3, and HClO4 at 140°C and diluted into HNO3. Element concentrations were determined using USGS terrestrial rocks as standards for calibration. Precision and accuracy of the technique, evaluated based on measurements of samples of known composition, are for 16 elements better than 10%.
