Types of Chromatography

by Ruhia

What if you finally had a lab at home and could experiment anytime? Would it be nice if you had lab equipment on hand? Now it’s possible, and it no longer has to be an “if.” One of the most helpful tools for the research and measurement of compounds is chromatography. By using the different types of chromatography, you’ll be surprised what you can quantify to make the best next step in research.

Read and learn more about the types of chromatography and how they work so you can get started on your next analysis. Let’s get into it!

What Is Chromatography?

Chromatography is an analytical technique used to separate, analyze, and identify different compounds in a mixture. It can be performed with a variety of media including gases, liquids, and solids.

It has become an invaluable tool in clinical chemistry and has been used for a variety of applications including:

  • Determining blood glucose levels
  • Identifying drug metabolites
  • Qualitative and quantitative analysis
  • Other mixtures

It remains an important part of chemical testing and continues to be a key tool in the pharmaceutical, medical, and industrial research fields.

The Different Types of Chromatography

Different types of chromatography are used in many situations. But it all depends on the components of the sample and the goals of the researcher. The most common forms of chromatography are:

Gas Chromatography

This technique involves using a carrier gas to move volatile components of a mixture over a bed of stationary material. The gases in the mixture interact with the stationary material, causing them to move at varying speeds.

This process is known as chromatographic separation and produces a chromatogram. The chromatogram can then be measured to identify and detect individual compounds in the sample.

GC is commonly used in a variety of applications including the identification of compounds in forensic, environmental, and pharmaceutical sciences.

Thin-Layer Chromatography

TLC is a useful separation technique to identify unknown compounds. It utilizes the differences in the component’s affinity for a layer of stationary phase to separate the components of a mixture.

This phase is commonly applied to a plate of glass, metal, or plastic. Compounds that have a higher affinity will move less than those with a lower affinity for the stationary phase.

Furthermore, this process is repeated to achieve optimal separation of the components. Finally, it can also be used to check for the presence of impurities in a sample.

Liquid Chromatography

Liquid chromatography works by mixing the sample with a solvent. It forces it through a column, which is made of a stationary material and a mobile phase.

The stationary phase is usually a solid, such as silica, while the mobile phase is a liquid or gas. However, this technique requires sophisticated equipment and complex methods.
