High efficiency gas-solid chromatographic columns
… columns was conducted. The first type (micropacked) can be defined as columns having an internal diameter less than 1 mm and a particle/column diameter ratio between 0.1 and O.3 and a packing density comparable to conventional packed columns. The second type, slurry packed gas …

Pressure-driven and electroosmotically-driven liquid chromatographic separations in packed fused silica capillaries
… flow is studied and the improved permeability of micropacked capillary columns is exploited in the manufacture of several 25 to 30cm columns which achieve high efficiencies with relatively low pressure drops. Van Deemter plots illustrate the performance characteristics of the columns. Finally, …
