Radioactivity Ge-68 - BIPM
The results of BIPM.RI(II)-K1.Ge-68 have been published in the KCDB. This is a comparison of the activity of Ge-68 using the SIR (International Reference System) method. The Final Report  also links the results obtained from CCRI(II)-K2.Ge-68 to BIPM.RI(II)-K1.Ge-68. This comparison is a continuous comparison within the field of Ionizing Razdiation.

CCQM-K122 - Anionic impurities and lead in salt solutions
The results of CCQM-K122 have been published in the KCDB. This is a comparison of anionic impurities (bromide and sulfate)and lead in salt solutions  within the field of Chemistry and Biology in which 14 state economies participated. Traceability systems in elemental analysis get their fundamental link to the SI via the purity determination of suitable metals or salts.

Key Comparison of Biogas - CCQM
The results of CCQM-K112 have been published in the KCDB. This is a comparison of the determination of components in biogas in the field of Chamistry and Biology. Biogas is of increasing importance world wide as an energy vector. It presents an environmentally friendly alternative to natural gas and contributes to reduction of the emission of greenhouse gases from fossil fuels.
The two mainstream approaches for producing biogas are fermentation and the gasification of biomass. This key comparison is about the macro composition of biogas from fermentation. Seven components were tested: methane, carbon dioxide, nitrogen, hydrogen, oxygen, ethane and propane in this project, in which 10 economies participated.
