How does column chromatography transform separation into purification?

Some points on how column chromatography transform separation into purification:

• During column chromatography, separated bands form at different positions in the column, and each collected fraction contains fewer impurities than the original mixture.
• As elution progresses, individual components exit the column at different times, allowing fractions to be collected without overlap.
• The identity of each fraction becomes clearer as separation progresses, rather than purity appearing all at once.
