Today scientists must deal with complex samples that either cannot be adequately separated
using one-dimensional chromatography or that require an inordinate amount of time for …

Twenty-eight extracts from 17 species of Australian native plants traditionally used as general
anti-inflammatory medicines by Australian Aboriginal people were examined for inhibition …

Using optical on-column visualization for the study of the migration of sample bands, the
radial variations of the local migration rate were studied in the region near the column wall. …

The interface between two fluids that have different viscosities and are percolating through
a porous bed is unstable. Sooner or later, a flow instability termed viscous fingering (VF) …

A 17 mm ID glass column, packed with YMC-15 (spherical C 1 8 silica, 30 μm particles) as
the stationary phase and used with carbon tetrachloride as the mobile phase provided a …

High performance liquid chromatography coupled with post column derivatisation (HPLC-PCD)
may be used to profile the antioxidant content of a sample. There are, however, …

Viscous fingering is a flow instability phenomenon that results in the destabilisation of the
interface between two fluids of differing viscosities. The destabilised interface results in a …

A new column technology – termed parallel segmented outlet flow was employed here to
illustrate gains in separation performance that are achievable by the active management of …

Narrow bore columns find advantage in HPLC applications when volumetric flow is important,
For example, for detection processes that are volume limited. Yet there are significant …

Viscous fingering is an important fluid transport phenomenon that manifests itself when two
fluids having different viscosities move in the same direction. Their interface is unstable and …
