Paper chromatography is a useful technique because it is relatively quick and requires only small quantities of material. Separations in paper chromatography involve the principle of partition. In paper chromatography, substances are distributed between a stationary phase and a mobile phase.

Chromatography separates dissolved substances by different interaction with (i.e., travel through) a material.

Planar chromatography is a separation technique in which the stationary phase is present as or on a plane. The plane can be a paper, serving as such or impregnated by a substance as the stationary bed (paper chromatography) or a layer of solid particles spread on a support such as a glass plate (thin-layer chromatography).
In chromatography, the retardation factor (R) is the fraction of an analyte in the mobile phase of a chromatographic system. [1] In planar chromatography in particular, the retardation factor R F is defined as the ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. [2]
The introduction of paper chromatography was an important analytical technique which gave rise to thin-layer chromatography. [13] Finally, gas-liquid chromatography, a fundamental technique in modern analytical chemistry, was described by Martin with coauthors A. T. James and G. Howard Smith in 1952. [14]
The Journal of Chromatography B is a peer-reviewed scientific journal publishing research papers in analytical chemistry, with a focus on chromatography techniques and methods in the biological and life sciences.
Thin layer chromatography (TLC) is a quick alternative to more complex chromatography methods. TLC can be used to analyze inks and dyes by extracting the individual components. [ 18 ] This can be used to investigate notes or fibers left at the scene since each company's product is slightly different and those differences can be seen with TLC.
