2. The ink used in a note left at a crime scene can be identified through paper chromatography. The chromatogram showing the components of the ink used in the note can be compared to chromatograms of known inks hopefully identifying the type and brand of ink used providing a clue to the crime.

3. It is used in the sequencing of DNA and RNA.
4. Paper chromatography is used as a qualitative analytical chemistry technique for identifying and separating colored mixtures like pigments.
5. It is used in scientific studies to identify unknown organic and inorganic compounds from a mixture.
6.In order to obtain a pure sample each component of the separated mixture, the separated spots on the finished and dried chromatogram can be cut out and re-dissolved.

Chromatography is used in chemistry in a number of applications:

1. Unknown substances left at a crime scene can be identified by separating the molecules that make them up. Matching this unknown chromatogram to chromatograms of known substances can help identify the unknown substance providing a clue to the crime.
