A combined experimental and theoretical study was performed to understand how the pore size of packing materials with pores 60–300 A˚ in size affects the separation of 5–50-mer oligonucleotides. For this purpose, we developed a model in which the solutes were described as thin rods to estimate the accessible surface area of the solute as a function of the pore size and solute size. |
