- Definition a technique for separating chemical substances by exploiting the differences in the rates at which they pass through a bed of a porous, semisolid substance Reference Encyclopaedia Britannica online > gel chromatography (article): http://www.britannica.com/eb/article-9036314/gel-chromatography (14/11/2007)
- Comment Separation is effected as the sample passes through a column which is filled with a porous material, typically an organic gel. Small molecules can penetrate the pores whereas large molecules are excluded. The path of the large molecules is thereby shorter and these are eluted first. The medium-sized molecules penetrate some of the pores and are eluted later. The smallest molecules, with a mean hydrodynamic radius smaller than the pores of the gel, can penetrate all of the pores. These are eluted last
