Nanometer control over the porous shell thickness of sub-2-μm-shell particles is investigated. Three seeded growth mesoporous thin shell particles for HPLC were prepared, with 0.05μm (or 50nm) porous shell layers: particle sizes 1.5μm (solid core diameters 1.4μm), 1.7μm (solid core

In this study, C18-silica monoliths were synthesized as a porous layer in open tubular capillary columns, to be cut later into microcartridges for the analysis of neuropeptides by on-line solid-phase extraction capillary electrophoresis with UV and MS detection (SPE-CE-UV and
