Abstract
A microflow cell comprising an outer cylinder disposed on the outer periphery of a cylindrical flow cell and having a flat surface on at least a light-entering surface, and a filling material inserted between the outer cylinder and the flow cell and a capillary electrophoresis method using such a microflow cell. Since the outer cylinder is provided on the outer periphery of the cylindrical flow cell and the gap between the flow cell and the outer cylinder is filled up with a filling liquid, the quantity of scattered light is reduced, thereby enabling the adoption of fluorometry in the analysis of capillary electrophoresis.
