chromatography columns

Chromatography columns are specialized devices used to separate mixtures into their individual components. Think of them as a vertical tube filled with a stationary material, like tiny beads. When a mixture is passed through, components travel at different speeds—some move quickly, others slowly—depending on how they interact with the stationary material. This separation allows scientists to identify, analyze, or purify specific substances within complex mixtures. The technique is widely used in fields like pharmaceuticals, environmental testing, and food safety to ensure products are pure and correctly composed.
