A polystyrene resin SEC column has a diameter of 8.8 mm and a length of 30 cm. The particle skeleton (solid portion) occupies 20% of the volume, the intraparticle pore space occupies 40% of the volume, and the interstitial volume (interparticle space) constitutes the rest. The column is operated at a flow rate of 1 mL/min What would the elution time of a very large protein (MW > 600 kDa) that is completely excluded from the pores be? What would...
