The Comite Consultatif pour la Quantite de Matiere (CCQM) was established by the Comite International des Poids et Mesures (CIPM) in response to the issue of international comparability and traceability of chemical measurements. At its second meeting, in 1996, the CCQM working group on metrology in chemistry decided upon international comparisons for organic compounds using isotope dilution mass spectrometry (IDMS). The first CCQM inter-comparison concerning the determination of a solution of (p,p'-dichlorodiphenyl) dichloroethylene using IDMS was carried out by eight national laboratories, including our institute. Two-level (low and high) sample solutions were provided by the pilot laboratory. Our results for high-level samples showed good agreement within 1% of the reference values. Further, we had attempted an IDMS measurement using three different types of mass spectrometers: a magnetic sector, a quadrupole and an ion trap for comparing the sensitivity or reproducibility among these instruments.
