Preparation of multicomponent mixtures to support carbon metrology

The Reference Gas Laboratory (LGR) of Portuguese Institute for Quality (IPQ) is participating in the project – Metrology Support for Carbon Capture Utilization and Storage (MetCCUS) under the new European Partnership on Metrology Program (EPM). The goal of this project is to develop a metrological infrastructure that enables monitoring and detection of carbon dioxide leaks in energy and industrial processes, in transport networks and also allow the support of a better understanding of the life cycle of carbon dioxide. The contribution of LGR involves the preparation of certified reference materials (CRM) to allow the measurement of impurities in CO2 with the associated uncertainties and metrological traceability. The study is focused on the impurities: SO2, H2S, CO, O2 and CH4. This work also involves the study of interferents based on the analytical methods used. These CRM will provide support for the calibration and validation of instrumentation used in carbon capture processes.
