A capillary array capable of being easily mounted on an electrophoresis apparatus without damaging the capillaries. The capillary array can include a plurality of capillaries that can be fixed via hollow electrodes on a load header in a matrix arrangement. The load header can be disposed on the electrophoresis apparatus. The capillary array can include a capillary frame onto which a capillary head and a detection portion can be detachably mounted. The structure allows the load header, the capillary head, the detection unit and other portions of the capillary array to be handled as a unit, thereby making it easier to mount the capillary array on the electrophoresis apparatus.

Capillary array and electrophoresis apparatus, and methods

The present invention easies a connection between electrodes of a capillary array device and a connection plate for supplying a high voltage to the electrodes. According to the present invention, a connection plateand hollow electrodesare connected without solder but via a spring force. Alternatively, the hollow electrodescan be connected to the connection plateby utilizing volume elasticity of the connection plate.
