Inter-laboratory calibration of international carbon isotope standards of n-alkane mixtures

During the last decade, compound-specific stable carbon isotope (CSIA) analysis has become a valuable tool for the discrimination among products of different geological origins. CSIA requires high accuracy of the isotopic signals. Here we present the results of three international n-alkane standards...

Description
Summary:During the last decade, compound-specific stable carbon isotope (CSIA) analysis has become a valuable tool for the discrimination among products of different geological origins. CSIA requires high accuracy of the isotopic signals. Here we present the results of three international n-alkane standards gained on our GC-C-IRMS instrument, elucidating that compound-specific carbon isotope analysis in our lab can be of international high quality.
