Alternative data reduction for precise and accurate isotope ratio determination via LA-MC-ICP-MS [PDF]
, 2008 An alternative approach for the evaluation of isotope ratio data using LA-MC-ICP-MS will be presented. In contrast to previously applied methods it is based on the simultaneous responses of all analyte isotopes of interest and the relevant interferences without performing a conventional background correction.
