Uses of chromatography


Chromatography is basically a set of techniques used in separation of mixtures into individual components. Its uses could keep us here for long so am just going to highlight the common one.

What are the uses of chromatography?

Chromatography has been applied in various fields and aspects of our lives. From things we do every day all the way to the medicine world and even in chemistry. The uses are as follows:-

  • Uses of chromatography in chemistry
  • Used in testing the purity of substances
  • Used in separation of compounds like chiral compounds that are very similar in many aspects and only differ in optical isomers
  • Commonly used to understand the relationship between individual components that make up a particular mixture
  • Generally used in the separation of mixtures


  • Uses of chromatography in medicine


  • Used in separation of ink and dyes
  • Detection of some drugs and alcohol in the blood is done using chromatography
  • Used in testing the purity of large amounts of pharmaceutical products as purity is very vital in this field
  • Used in separation of chiral compounds in pharmaceutical products. This is because some chiral compounds have medicinal values while others are harmful to the human body
  • Paper and gas chromatography are employed in essential medical analysis like DNA and RNA analysis which are the basis of medicine.
  • Used in forensic science to determine burnt particles and mainly to identify flammable chemicals that might be the cause of explosions


  • Chromatography uses in everyday life


  • Used in laboratories to determine the purity of any substance/ compound made.
  • Checking the levels of any harmful compounds or toxics in water or food
  • Used to check the levels of adulterants in any manufactured products
  • Determines the amount of reactants or products
