SEC operates also within a preparative way by trapping the scaled-down molecules from the pores of the particles. The bigger molecules only move through the pores as they are also big to enter the pores. Larger sized molecules thus stream in the column more rapidly than more compact molecules: that's, the lesser the molecule, the lengthier the retention time.
Liquid chromatography is without doubt one of the a few most important branches of chromatography. It entails a little volume of liquid sample placement into a tube packed with porous particles.
