Paper chromatography. This is the technique from which thin layer chromatography was developed. It uses cellulose paper (filter paper) instead of the TLC adsorbent and does not require a backing like the plastic
Chromatography on pure paper may be considered an establishment of a dynamic equilibrium or partition between solution (adsorption) in a fixed semi-aqueous layer upon the cellulose fiber and solution in the moving organic phase. The solvent chosen should be determined by the nature of the mixture ...

A vertical glass tube used in column chromatography; a mixture is poured in the top and washed through a stationary substance where components of the mixture are adsorbed selectively to form colored bands Post (Basketball) A position usually taken by the center close to the basket or below the...
If you give us 1-9, we could suggest a thin-layer chromatography (TLC) system (using silica gel plates) to help you scout for a suitable LC system. There is more than enough expertise on the forum to guide you through this, but very difficult to hit a moving target. ...

In this paper we investigate the relationship between solute retention and mobile phase composition in reversed-phase liquid chromatography over the entire range of composition, with emphasis on mobile phases with a high water content. It will be shown that a quadratic relationship between the logarith...
Column chromatography has also been shown to effectively remove aggregates. Combination of bind-and-elute mode by cation exchange chromatography (CEX) and flow-through mode by anion exchange chromatography (AEX) is widely used to remove impurities and aggregates for mAb processes, and it is ...
