SEM image and EDS mapping of particles in online prepared substitution fluid. SEM image and EDS mapping of particles in online prepared substitution fluid sampled from the final ETRF after 3 months of use, commercial sterile substitution fluid, and 5% glucose injection. In EDS mapping (elemental analysis), brown is C, pink is O, and turquois blue is Si. SEM, scanning electron microscopy; EDS, energy-dispersive X-ray spectrometry; ETRF, endotoxin-retentive filters
