Abstract
A process for analyzing a sample by a capillary electrophoresis method is provided that allows the apparatus to be reduced in size, allows a high analytical precision to be obtained, and can be carried out easily. The analytical process of the present invention is a process for analyzing a sample by a capillary electrophoresis method. The analytical process includes preparing a capillary tube to be used for the capillary electrophoresis method, and performing electrophoretic separation of a complex of a sample and an anionic group-containing compound that are bonded together, in the capillary tube, wherein the capillary tube includes an anionic layer that is formed of the anionic group-containing compound and that is coated on the inner wall of the capillary tube, and the anionic layer is fixed to the inner wall of the capillary tube by a covalent bond.
