This document describes the result of a key comparison for propane in nitrogen. The nominal amount-of-substance fraction of propane is 1000 μmol/mol. The comparison aimed to assess the measurement capability of participants in gas analysis. Nine NMIs or DIs participated in the comparison. CERI participated in a key comparison CCQM-K111—propane in nitrogen, and coordinated this key comparison. Therefore, every participants' results of this comparison are linking to the CCQM-K111. Gravimetric values of the samples were used as key comparison reference values (KCRVs). Measured values of eight participants were within ± 0.25 % of the KCRVs. Many participants reported purity or impurity analysis of materials. These results are also able to assess the participants' capability of the analysis.
