summarize concisely: Chromatography is an analytical technique used to separate the components of a mixture based on their different interactions with two phases: a mobile phase and a stationary phase. The mobile phase is the fluid that moves through the system, such as a liquid or gas, carrying the mixture. The stationary phase is the fixed medium that the mobile phase moves through, which can be a solid or a liquid supported on a solid. Intermolecular interactions, such as hydrogen bonding, van der Waals forces, and ionic and dipole interactions, play a crucial role in chromatography. As the mobile phase carries the mixture through the stationary phase, each component interacts with the stationary phase to different extents based on these forces. Components that interact weakly with the stationary phase travel faster, while those that interact more strongly move slower. This differential movement results in the separation of the mixture's components, allowing for analysis and identification
