Quickly Understand High Performance Liquid Chromatography (HPLC)

Learn that HPLC is a chromatography technique that separates mixtures using a mobile phase flowing through a stationary phase. Understand that high pressure (up to 400 atmospheres) enables faster separation with smaller particles and better resolution compared to standard column chromatography.

Connect the mobile phase solvent to a delivery pump that will pressurize and push the solvent through the column at high pressure to accelerate the separation process.

Add the liquid sample through a separate tube into the HPLC system where it will be carried along with the mobile phase.

Allow the sample and mobile phase to flow through the column containing the stationary phase, where different components interact at different rates and separate based on their chemical properties.

Use a detector to convert the amount of each separated component into electrical signals for quantification and identification of the sample constituents.

Use a non-polar solvent with polar silica particles as the stationary phase, causing polar compounds to move slowly and non-polar compounds to move quickly through the column.

Use a polar solvent with modified non-polar silica particles as the stationary phase, causing non-polar compounds to move slowly and polar compounds to move quickly through the column.
