2025年1月30日 · Stationary phase, in analytical chemistry, the phase over which the mobile phase passes in the technique of chromatography. Typically, the stationary phase is a porous solid that is packed into a glass or metal tube or that constitutes the walls of …

In chromatography, the separation of components in a mixture is achieved through the interaction between the mobile phase and the stationary phase. These two phases play crucial roles in determining the efficiency and selectivity of the separation process.

2024年12月28日 · At its core, HPLC relies on the differential interaction of sample components with two phases: Mobile Phase: The phase that moves through the chromatographic system, transporting the sample. Stationary Phase: The phase that remains fixed in place and interacts with the sample components, causing them to separate.

2024年4月16日 · Chromatography is a method by which a mixture is separated by distributing its components between two phases. The stationary phase remains fixed in place while the mobile phase carries the components of the mixture through the medium being used.

2023年1月24日 · The stationary phase is a solid particle or a thin liquid film coated on either a solid particulate packing material or on the column’s walls. In planar chromatography the stationary phase is coated on a flat surface—typically, a glass, metal, or plastic plate.

2024年1月11日 · Stationary Phase. The stationary phase is a crucial component of chromatography that interacts with analytes as they pass through, leading to separation. Solid, liquid, or gas can be held over a supporting medium. The stationary phase interacts with various mixture components based on the polarity, affinity, size, and charge.

In liquid–liquid chromatography the stationary phase is a liquid film coated on a packing material, typically 3–10 μm porous silica particles. Because the stationary phase may be partially soluble in the mobile phase, it may elute, or bleed from the column over time.

Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase.

In general, three primary characteristics of chemical compounds can be used to create HPLC separations. They are: First, let’s consider polarity and the two primary separation modes that exploit this characteristic: normal-phase and reversed-phase chromatography.

Chromatography relies on two different 'phases': stationary phase Phase in chromatography that does not move, for instance, the paper in chromatography. mobile phase Phase in...
