The separation principle in SEC relies on the entirely, or partly penetrating with the higher molecular pounds substances on the sample into the porous stationary-stage particles for the duration of their transportation by means of column. The cellular-phase eluent is selected in this type of way that it totally prevents interactions Along with the stationary section's surface. Beneath these ailments, the smaller the size on the molecule, the greater it can penetrate inside the pore House as well as the movement through the column can take lengthier. On the flip side, The larger the molecular size, the upper the likelihood the molecule won't thoroughly penetrate the pores of your stationary section, and perhaps vacation around them, Therefore, is going to be eluted previously.
