General structure and component of a chromatographic system

A stationary phase – typically an aqueous buffer with sufficient ionic strength to maintain a soluble protein.

A column -

An injector system: To deliver test samples to the top of the column in a reproducible manner.

A detector with data acquisition - To give a continuous record of the presence of the analytes in the eluate as it emerges from the column.

A fraction collector: For collecting the separated analytes for further biochemical studies.
