What Type of Compounds Can Be Separated by Paper Chromatography?

Points on type of compounds separated by paper chromatography: Paper chromatography separates mixture components that can dissolve in a liquid mobile phase and migrate on a paper medium during chromatographic separation.  Soluble compounds interact with both the liquid solvent and the paper surface as they move across the paper.  This requirement ensures that separation occurs on paper through a liquid-driven chromatographic process.

 Definition of Paper Chromatography: Paper chromatography is a chromatographic technique in which components of a mixture are separated on a sheet of paper using a liquid mobile phase. In this method, the paper functions as the stationary support while a liquid solvent moves across it to enable separation. The technique requires direct interaction between the paper medium and a liquid phase for separation to occur. Separation is defined by taking place on the paper surface itself rather than within columns, coated plates, or gaseous systems.

Also find out more information on definition of gel filtration to learn more about it. 

What is Gel Filtration Chromatography?

Definition of Gel Filtration Chromatography Gel filtration chromatography is a separation technique that separates molecules based on their size using a porous gel matrix. In gel filtration chromatography, larger molecules elute earlier because they are excluded from the pores of the gel matrix.

What is Height Equivalent to a Theoretical Plate (HETP) in Chromatography?

Definition of Height Equivalent to a Theoretical Plate (HETP) Height Equivalent to a Theoretical Plate (HETP) in chromatography is the length of column required to achieve one theoretical separation stage. HETP decreases as separation efficiency increases because a shorter column length is needed to achieve each theoretical separation stage. HETP is calculated by dividing column length by the number of theoretical plates, confirming it represents column length per separation stage. Lower HETP values indicate that solute bands undergo effective separation over shorter column segments, reflecting one theoretical plate per reduced length.
