Abstract:
1. A process for analyzing glycated hemoglobin in a sample by a capillary electrophoresis method comprising: providing a sample comprising glycated hemoglobin, preparing a capillary channel for capillary electrophoresis, and performing electrophoretic separation of a chemical complex comprising the hemoglobin and a first anionic compound that is present in a running buffer solution at a pH in a range of 4.5 to 6 in the capillary channel, wherein the capillary channel comprises an inner wall coated with an A layer and a B layer that coats the A layer, wherein the A layer is covalently bonded to the inner wall and consists of a cationic compound, and the B layer consists of a second anionic compound which may be the same or different from the first anionic compound, and wherein the first anionic compound is an anionic polysaccharide.
