As Figure 7 suggests, the use of 300 pore size stationary phases does have a practical limit for large molecules and you should be mindful of the sample’s complexity before considering the separation of large macromolecules on this type of phase. Proteins are large macro molecules and diffuse slowly (small diffusion rate constant). Proteins are also more likely to cause a steric hindrance once they bind to the pore surface.
