From Pore Scale to Column Scale Dispersion in Capillary Silica Monoliths

We study time and length scales of eddy dispersion in 100 μm i.d. capillary silica monoliths. First, the monolith’s macropore morphology was visualized over complete column cross sections by confocal laser scanning microscopy, revealing a wall region with large voids (with a lateral dimension of up...
