Abstract
Eight out of twelve laboratories (67%) participating in the nitrogen analysis reported {sup 15}N-data within the control limits for the enriched plant sample and eight out of nine (89%) participating laboratories for carbon analysis reported {sup 13}C isotopic abundance results within the control limits for this test sample. The reported analytical data and WEPAL evaluation of the {sup 15}N enriched plant material produced by SWMCNL is shown. All participants received a certificate of participation. Worldwide comparison of stable {sup 15}N and {sup 13}C isotope measurements will provide confidence in the laboratory's analytical performance and is hence an invaluable tool for external quality control. It is hoped that in the future more stable isotope laboratories will make use of this unique opportunity to assess their analytical performance and provide evidence of the high quality of their analytical data.
