There are several types of HPLC (High Performance Liquid Chromatography) used in analytical chemistry.

• Reverse Phase HPLC

• Normal Phase HPLC

• Ion Exchange HPLC

• Size Exclusion HPLC

• Affinity HPLC

• Chiral HPLC

• Hydrophilic Interaction Chromatography (HILIC)

• Hydrophobic Interaction Chromatography (HIC)

• Reversed-Phase Ion Pairing Chromatography (RP-IPC)

• Fast Protein Liquid Chromatography (FPLC)

The column used in HPLC is a crucial component that separates and analyzes compounds in a liquid sample.

• The column in HPLC is packed with stationary phase particles that interact with the sample components.

• Different columns with varying properties are used depending on the analytes and separation requirements.

• Common types of columns include reverse phase, normal phase, ion exchange, and size exclusion columns.
