The use of this technique was limited till the mid 20th century when the researchers Martin and Synge developed Partition chromatography to separate chemical substances with minimum separating coefficients.
Paper Chromatography and Thin-layer Chromatography are the two among many chromatographic techniques that were developed with time and have been used continuously in different departments for separation of components. Paper Chromatography is a Solid-Liquid partition based technique for the component separation based on their polarity towards both the phases. The stationary phase in this technique is the Cellulose based filter paper while the mobile phase is the liquid.
TLC is a Solid-Liquid Adsorption based technique in which the components of a mixture are separated based on their polarity towards both phases. The stationary phase in this technique is glass-coated with the silica gel layer while the mobile phase is the liquid. Thus, the column packed with the matrix material acts as the stationary phase and the wash buffer applied to the column acts as the mobile phase.
If the molecules are separated based on the size, the packing material is packed in a manner that it leaves pores for the compounds to travel through. Thus, the larger molecules that cannot flow through the pores are eluted first, whereas the smaller molecules take much longer time to elute. If the molecules are separated based on their charge, the stationary phase will contain either an anion or cation exchanger to which the compounds will get attracted based on their charge.
Thus during the washing step, the non-bound compounds will be eluted. Upon adding the elution buffer, the bound charged compounds will be eluted. The detection of these eluents is mostly based on spectrophotometric techniques.
Paper chromatography, TLC and column chromatography are separation techniques used to separate biomolecules such as proteins, amino acids and carbohydrates mainly monosaccharides.
Paper chromatography uses a cellulose paper as the stationary phase, and the mechanism of separation is based on solid-liquid adsorption. TLC also uses solid-liquid adsorption mechanisms. The molecules are separated on the stationary phase, depending on their solubility in the mobile phase.
Column chromatography uses physical properties such as size, shape, charge and the molecular weight of the compound to separate. The column packed with the matrix material acts as the stationary phase, whereas the wash buffer acts as the solvent phase. This is the difference between a paper thin layer and column chromatography. Clark , Jim. Available here 2. Coskun, Ozlem. Available here. Samanthi Udayangani holds a B.
