The main components of a column chromatography setup include:

• Column: A vertical tube that holds the stationary phase.
• Stationary Phase: The material packed inside the column (e.g., silica gel).
• Mobile Phase: The solvent or mixture of solvents that flows through the column.
• Sample: The mixture that is to be separated.
• Fraction Collector: A device that collects the eluted fractions separately.
