20.500.12556/DKUM-27469 Pressure drop characteristics of poly(high internal phase emulsion) monoliths Today, monoliths are well-accepted chromatographic stationary phases due to several advantageous properties in comparison with conventional chromatographic supports. A number of different types of monoliths have already been described, among them recently a poly(high internal phase emulsion) (PolyHIPE) type of chromatographic monoliths. Due to their particular structure, we investigated the possibility of implementing different mathematical models to predict pressure drop on PolyHIPE monoliths. It was found that the experimental results of pressure drop on PolyHIPE monoliths can best be described by employing the representative unit cell (RUC) model, which was originally derived for the prediction of pressure drop on catalytic foams. Models intended for the description of particulate beds and silica monoliths were not as accurate. The results of this study indicate that the PolyHIPE structure under given experimental condition is, from a hydrodynamic point of view, to some extent similar to foam structures, though any extrapolation of these results may not provide useful predictions of pressure versus flow relations and further experiments are required. organic chermistry polymers monoliths PolyHIPE hydrodynamic properties pressure drop organska kemija polimeri monoliti PolyHIPE hidrodinamske lastnosti padec tlaka true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:18:53 2012-06-01 11:18:53 2022-04-15 03:44:55 2019-07-10 12:17:37 2007 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 547:678 11099670 0021-9673 URN:SI:UM:DK:Z0KC9V2A http://dx.doi.org/10.1016/j.chroma.2007.01.003 1 https://dk.um.si/Dokument.php?lang=slv&id=36768 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
