Packed column definition
WebIn standard packed absorption columns, a gas mixture travels up through a gas absorption tower and the solute is transferred to the liquid phase and thus gradually removed from the gas. The liquid accumulates solute on its way down through the column. Multicomponent mass-transfer effects, nonisothermal gas absorption, and axial dispersion ... WebJul 6, 2024 · 10.

WebAug 15, 2024 · Columns can be packed with solids such as silica or alumina; these columns are called homogeneous columns. If stationary phase in the column is a liquid, the column is deemed a bonded column. Bonded columns contain a liquid stationary phase bonded to a sold support, which is again usually silica or alumina. WebOct 18, 2024 · Packed columns and capillary columns are two types of columns that are used as the stationary phase during chromatographic extractions.
