The simplest method is to use a syringe, and the sample is introduced to the flow of eluent.An injector is placed next to the pump.Because of this piston motion, it produces “pulses”. Most pumps used in current LC systems generate the flow by back-and-forth motion of a motor-driven piston (reciprocating pumps).High-pressure generation is a “standard” requirement of pumps besides which, it should also to be able to provide a consistent pressure at any condition and a controllable and reproducible flow rate.

The pump is positioned in the most upper stream of the liquid chromatography system and generates a flow of eluent from the solvent reservoir into the system.

The development of HPLC led to the development of the pump system.

The chromatogram allows the identification and quantification of the different substances.

At the end of this operation/run, a chromatogram in the HPLC software on the computer is obtained.After leaving the column, the individual substances are detected by a suitable detector and passed on as a signal to the HPLC software on the computer.

Subsequently, the individual components of the sample migrate through the column at different rates because they are retained to a varying degree by interactions with the stationary phase.

a small tube or a capillary made of stainless steel, the sample is injected into the mobile phase flow from the pump to the separation column using a syringe.

Via a valve with a connected sample loop, i.e.

The mobile phase, on the other hand, is a solvent or solvent mixture which is forced at high pressure through the separation column.

The stationary phase is a granular material with very small porous particles in a separation column.The purification takes place in a separation column between a stationary and a mobile phase.Principle of High-Performance Liquid Chromatography (HPLC)
