Capillary phase
WebJul 19, 2007 · We use density functional theory to study the capillary phase behaviour of a discotic system of colloidal platelets that are confined in a planar slit pore. The model plates have circular shape, continuous orientations and vanishing thickness; they interact via hard-core repulsion with each other and with the walls which induces homeotropic wall … WebJan 19, 2024 · Capillary pressure ( Pc) is defined as the difference in pressure across the meniscus in the capillary tube. Put another way, capillary pressure is the amount of …

WebCapillary columns are gas chromatography (GC) columns that have the stationary phase coating their inner surfaces rather than being packed into the cavity. Capillary GC … people born on december 20 1962WebCapillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the water molecules. The same attraction between water molecules that is responsible for surface tension causes the leading water molecules to pull the neighboring water molecules along behind them. toehold switch是什么WebJan 24, 2024 · A capillary, or open tubular column is constructed from fused silica and is coated with a protective polymer coating. Columns range from 15–100 m in length with an internal diameter of approximately 150–300 μm.
