Molecules migrate into pores inside of a porous media and so are segregated primarily based on their more info own measurement in comparison to the pore dimensions. Big molecules elute to start with, accompanied by smaller kinds.

SEC is effective also in a preparative way by trapping the smaller molecules within the pores of a particles. The bigger molecules basically move through the pores as These are far too substantial to enter the pores. Much larger molecules thus stream in the column more rapidly than scaled-down molecules: that is definitely, the scaled-down the molecule, the more time the retention time.

Slim-layer chromatography is actually a “reliable-liquid adsorption” chromatography. In this method stationary stage can be a reliable adsorbent compound coated on glass plates. As adsorbent substance all good substances applied. in column chromatography (alumina, silica gel, cellulose) is usually used. In this process, the cellular stage travels upward through the stationary phase The solvent travels up The skinny plate soaked With all the solvent by the use of capillary click here motion.
