Ultrahigh-Efficiency Protein Separations with Submicrometer Silica Using Slip Flow

Ultrahigh-Efficiency Protein Separations with Submicrometer Silica Using Slip Flow

Mary J. Wirth;Bingchuan Wei;Benjamin J. Rogers
October 1st 2012

Professor Mary Wirth and graduate students Bingchuan Wei and Benjamin Rogers from Purdue University demonstrate a quantum leap in protein column efficiency. Using colloidal silica particles of submicrometer diameters (470 nm), they obtained plate heights that were as much as 15-fold lower than the theoretical limit for Hagen-Poiseuille flow.
