IsotopeMaker: A Matlab program for isotopic data reduction

Mass fractionation during isotope measurement by mass spectrometer hinders the acquirement of true isotopic composition and tedious and complex mathematical calculations are required to correct for mass bias. This study provides a Matlab program named IsotopeMaker for convenient isotopic data reductions. IsotopeMaker has two main aspects of application. For in situ LA-MC-ICP-MS isotopic analyses, IsotopeMaker can process Sr, Nd and Hf isotope data. For double spike data, IsotopeMaker provides a fast and convenient mass bias correction for all elements that have at least four isotopes. The visualization windows of IsotopeMaker make it easy to operate. Isotopic Sr, Nd and Hf data of a modern coral, a reference zircon and an in-house apatite and Mo isotopic data measured using the double spike method have been used to test the program capability.
