| fussnote | A system for coupling amperometric detection with capillary electrophoresis (CE) is described. The interface is formed by fracturing the capillary followed by covering the fracture with a thin layer of cellulose acetate (CA) fihn. The porous CA joint enables off-column amperometric detection to be performed without adverse effects from the high electrophoretic voltage. The primary advantage of this CA joint is its simple construction. The performance of the CE-amperometric detection system was evaluated with hydroquinone. A detection limit of 8 . 10^-^8 M or 0.17 fmol with a theoretical plate number exceeding 90 000 was obtained. Application of the system to the separation and detection of aminophenols, catecholamines and catechol was also demonstrated. |
