Capillary electrochromatography (CEC) combines the principles used in HPLC and CE. The mobile phase is driven across the chromatographic bed using electroosmosis instead of pressure (as in HPLC). Electroosmosis is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane or any other fluid conduit.

Then the total volume of pickup at a maximum (unless drawing the sample while descending into the vial) would be 6.25uL (20ga: 4.41uL; 30ga: 2.61uL). At such a low volume, you would have to take
C18 HPLC columns are the most preferred as they offer an excellent range of hydrophobic separation power along with high surface area coverage. C8 HPLC columns are used when less retention compared to a C18 is needed. C4 and C5 HPLC columns are commonly used to separate large macromolecules such as proteins.
