Measurement of Interstitial Space Dispersion in Packed Bed Columns: Comparison of Superficially Porous and Fully Porous Particles
Kim Vanderlinden, Ken Broeckhoven, and Gert Desmet
Superficially porous particles have demonstrated separation efficiency gains compared to totally porous particles. The total pore blocking technique provides the purest possible measure of column packing quality. Here, we explain this technique and show what it has revealed.
