Fluidized bed chromatography
WebJun 5, 2024 · If the contact time is acceptable, you may be done. I would generally use a bed L/D of 1.5 to 2; but it depends on pressure drop, contact time, ability to prevent short circuiting (longer beds are ... A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidized bed is to pump pressurized fluid into the particles. The resulting medium then has many properties and characteristics of normal fluids, such as the ability to free-flow …
