Applications of ICP magnetic sector multicollector mass spectrometry to basic energy research. Progress report, December 1, 1993--August 31, 1994
The prototype ICP magnetic sector multicollector mass spectrometer has been installed and commissioned at the University of Michigan. Following performance evaluation and instrument characterization, the absolute abundances of isotopes of tin have been measured with precisions unproved by up to an order of magnitude over those of currently accepted, values. An efficient chemical separation technique for In and Sn in Zn, Cu and Fe sulfides and in silicate matrices has been successfully developed. The predicted {sup 115}Sn anomaly that results from the decay of {sup 115}In, has been measured in sulfides. Precise isotopic measurements of molybdenum, tellurium, hafnium, tungsten and platinum have been made. A new ND-YAG laser ablation microsampling device on line to the mass spectrometer for in situ isotopic analysis at high precision has been commissioned and tested with accurate measurements of Sr, W and Pb on standard silicate materials.
