## Abstract A novel tentacle‐type polymer stationary phase covalently modified with branched polyethyleneimine (PEI) was developed for peptides and proteins separations by open‐tubular CEC (OT‐CEC). The preparation procedure included the silanization of capillary inner wall, __in situ__ graft polym
