COMMISSION ON ISOTOPE SPECIFIC MEASUREMENTS AS TRACEABLE REFERENCES (II.4)

Number: 240/12/98

Title: Carbon Isotope Ratio in CO₂

Series: International Measurement Evaluation Programme (IMEP-8)

Coordinator(s): L. Van Nevel and P. Taylor

Completion Date: 2000 - Project Completed

Objective:
In this program, The Institute for Reference Materials and Measurements (IRMM), which coordinates IMEP is focusing on carbon isotope ratios in CO₂. Geochemistry, clinical and food chemistry laboratories will be invited to participate.

Two samples with different carbon ¹³d_VPDB values (between 0 and -30 ⁰/₀₀ ) will be made availabale to the participants. The samples will be supplied in two 1000ml containers, together with a pressure reducing valve.

Progress:

This project was presented at a poster session at the IUPAC Congress/GA July 2001
