Detection

Among the numerous HPLC detectors, only a limited number can reasonably be applied in SEC. One has to distinguish between concentration detectors and molar mass detectors.

• The response of a concentration detector is determined by the concentration of the solute in the mobile phase.

• The response of a molar mass detector depends on molar mass of the solute, as well as on concentration.

Ve = Vi # VpKsEcKrepKLAC

In ideal SEC, repulsion and adsorption should be absent, hence Krep as well as KLAC should equal unity.
