Finding out about the substance by using this analytical method gives us the Rf values. Which is also known as the retention factor. The use of chromatography paper is used during investigations at the crime scene where unknown substances are left behind at the crime scene which can be tested with the help of ph papers. The sequencing of RNA and DNA can be done with this method. Coloured pigments can be separated with the help of chromatography paper which is usually used in qualitative analytical chemistry. You can the pure samples of each component in the mixture by cutting out the strips on the paper where the component has been absorbed and redissolve it.
The paper chromatography is based on the different rates of migration of liquids on sheets of paper. It has proved to be an inexpensive technique which has been used in laboratories all over the world to help in the above mentioned processes successfully. Paper chromatography has now been replaced by thin layer chromatography because it is easier to install. The paper chromatography involved the use of cellulose paper to separate the components of the solvent which is based on the difference in the polarity if the substances.
