- •
75 μm i.d. columns are slurry-packed with 1.3 μm frictional, cohesive particles.
- •
The slurry concentration is increased gradually from 5 to 50 mg/mL.
- •
Packing microstructure is reconstructed using confocal laser scanning microscopy.
- •
Increased slurry concentrations suppress transcolumn bed heterogeneities.
- •
Too concentrated slurries favour the formation of larger voids in the packing.
