Despite the significant advantages of capillary isoelectric focusing over gel isoelectric focusing, widespread acceptance of the technique as a replacement for gel isoelectric focusing has not occurred. Several factors contribute to capillary isoelectric focusing’s slower-than-expected adoption; perhaps the most important are the performance and procedural difficulties introduced when capillary...

Protein adsorption to capillary walls is one of the major complications in protein analyses with capillary electrophoresis (CE). Coating the capillary with different materials is used to reduce the adsorption. This chapter overviews different approaches used for capillary coating and concentrates on those utilizing Si-O and Si-C covalent bonds. The apparatus and methods are presented for capill...

We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two-phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves contradicts the theoretically predicted force balanc...
