Fluid Flow Cell for time-resolved tomography experiments at Mogno beamline of Sirius

Abstract The advent of 4 th generation synchrotron sources has significantly enhanced the capabilities of these facilities for conducting time-resolved experiments. This advancement is crucial for scientific studies that seek to understand not only the final results but also the underlying processes involved in experiments. At the Brazilian Synchrotron Light Laboratory (LNLS), the Mogno beamline is operational, equipped with dual energy, zoom, and time-resolved X-ray tomography capabilities. The latter presents specific challenges in preparing sample environments that meet both the beamline’s requirements and the experimental needs of users. This work introduces a 3D-printed Fluid Flow Cell designed for consolidated porous samples, allowing for the monitoring of sample evolution over time during the injection of liquid fluids. The cell was commissioned as part of a proposal to investigate the interaction between HCl and sandstones in the context of CO 2 mineralization. Results from this study enabled the tracking of pore size distribution changes and the calculation of mineral dissolution rates, thereby providing valuable insights for researchers interested in exploring the dynamics of fluid-porous material reactions.
