In one of the labs, you separated blue dextran (approximate molar mass 2,000,000 g/mol) and sodium salt of fluorescein (molar mass 376.28 g/mol) using size-exclusion chromatography. Based on the knowledge gained from that experiment, which of the following is a TRUE statement? (You need to be able to explain each option. Understand the logic) Blue dextran molecules are eluted first out of the column first, because these molecules are too big to fit inside the pores and hence they flow through the interparticle space Blue dextran molecules are eluted first out of the column, because these molecules pass through the pores of the stationary phase gel particles Fluorescein molecules are eluted first out of the column, because these molecules pass through the pores of the stationary phase gel particles Fluorescein molecules are eluted first out of the column, because these molecules pass through the pores of the stationary phase gel particles
