Webb1 jan. 2001 · If the upward velocity is greater, the column should pack, usually with an impact velocity above the fall velocity. Observation of a glass column confirmed that the surface was perfectly flat all the time the column packed. The bed did not collapse when the flow was switched off. In order to hold the dilute slurry (usually 1-5 % w/v), a sample ... Webb8 juni 2013 · Fused silica capillary columns of the internal diameter of 320 μm were packed with the Nucleosil C18 stationary phase of 5 μm using the slurry packing method. The time of the bed compaction phase, packing pressure, and the use of ultrasound varied to study their influence on the column performance. Van Deemter curves were measured and …
WebbIn these reactors, slurry is circulated using a high pressure slurry pump through the ejector and reactors are usually operated as dead-end reactors. Ejector loop reactors offer … WebbConsidering packing a 50% slurry to a target bed height of 20 cm at a CF of 1.15, an inaccuracy of ± 2% in the slurry concentration can cause the final packed bed height to vary between 19.2 and 20.8 cm. Appropriate bed compression and resin slurry concentration ensure: Stable bed, especially at high flow velocities.
Webbpacking devices do not work well for packing POROS® resins. Prepare the slurry POROS® resins (except POROS® R 150 and R 250 resins) are supplied as approximately 56% slurry in 20% ethanol or buffered ethanol. When packed at 3 bar, a 1.8‐L slurry volume yields a 1‐L packed bed volume.
