Declining European natural gas resources and increasing legislation mean that diversification towards ‘non-conventional gases’ is essential. Accurate and traceable measurements of the composition of non- conventional gases are required to ensure gases can be transported in existing pipeline networks, and used with existing appliances. The EMRP ‘Characterisation of energy gases’ project is successfully developing a metrology infrastructure to underpin these measurements. New standards and methods have been developed for biogas composition, biogas impurities, coal mine gases, refinery gases and environmentally-friendly odorants. The project is set to conclude in 2013 with the challenging analysis of a series of real non-conventional gas samples.
Core capability tables list the skills and experiences, which at least partially are needed to successfully carry out a specific analytical task within the IAWG. The required skills and experiences, so-called core capabilities (CC), are identified for each analytical procedure. The summarized CC tables are listed in the appendix of each report on the corresponding key comparison or pilot study. These CC tables enable us to demonstrate that we have the analytical procedure we claim under control by means of other Key Comparison, which do not exactly meet the claimed calibration and measurement capability. This is especially important for: a) fields where no Key Comparison is available, b) Revision of CMC claims or c) when a participation in a Key Comparison was not possible.
CCQM-P149 is an attempt to obtain a snapshot on actual procedures the NMIs and DIs within CCQM-IAWG applied to the purity characterization of their “fit for purpose” elemental Standards. This presentation describes how the results of CCQM-P149 may be used to underpin calibration and measurement capabilities being claimed in the BIPM database.
