Fundamentals of High Performance Liquid Chromatography

An Introduction

High performance liquid chromatography (HPLC) is a powerful technique for separating and analyzing complex mixtures of compounds. It is used in a wide variety of applications, including pharmaceutical, environmental, and food analysis.

HPLC works by passing a sample through a column packed with a stationary phase. The sample components interact with the stationary phase to different degrees, causing them to separate. The separated components are then detected and quantified.

HPLC is a versatile technique that can be used to analyze a wide variety of compounds. It is also a relatively fast and efficient technique, making it ideal for routine analysis.

The Basics of HPLC

The basic components of an HPLC system include:

• A pump to deliver the mobile phase
• A column packed with a stationary phase
• A detector to detect the separated components
• A data acquisition system to record and analyze the data

The mobile phase is a solvent or mixture of solvents that is used to carry the sample through the column. The stationary phase is a solid material that is coated onto the inside of the column. The detector is a device that measures the concentration of the separated components in the mobile phase. The data acquisition system is a computer that records and analyzes the data from the detector.

HPLC Columns

The column is the heart of the HPLC system. It is responsible for separating the sample components. HPLC columns are available in a variety of sizes and shapes. The most common type of column is the packed column. Packed columns are filled with a solid support material, such as silica gel or alumina. The support material is coated with a thin layer of stationary phase.

Another type of column is the monolithic column. Monolithic columns are made from a single piece of porous material. The pores in the monolithic column are coated with the stationary phase.

HPLC Detectors

There are a variety of different detectors that can be used with HPLC. The most common type of detector is the ultraviolet (UV) detector. UV detectors measure the amount of light that is absorbed by the sample components.

Other types of detectors include:

• Fluorescence detectors
• Mass spectrometers
• Refractive index detectors
• Electrochemical detectors

HPLC Applications

HPLC is used in a wide variety of applications, including:

• Pharmaceutical analysis
• Environmental analysis
• Food analysis
• Forensic analysis
• Clinical chemistry

HPLC is a powerful technique that can be used to analyze a wide variety of compounds. It is also a relatively fast and efficient technique, making it ideal for routine analysis.
