Will my analyte absorb to the polymer used in the Controlled or Zero Flow coated capillaries for CE?

The Controlled and Zero EOF Capillaries usually produces a very low sample to polymer interaction (wall) and absorption.

Your analytes could be different however as it will depend on the hydrophobicity of your analyte. The more hydrophobic and neutral, the more chance it will be adsorbed. If it is charged it is not likely to stick.
