Abstract:
1. A capillary array comprising: a plurality of capillaries for holding a separation medium for separating a sample; a detecting portion for maintaining alignment of the capillaries; a capillary head for bundling and holding capillaries to one end of the capillaries; and a load header including an insulated holder, a conductive connection plate and an insulating member and for supporting tubular electrodes, wherein the insulated holder is provided at sample injection end portions of the capillaries; the tubular electrodes are fixed to the insulated holder, to allow insertion of sample injection end portions of capillaries; the conductive connection plate has bores for insertion of the tubular electrodes, supported by the insulated holder and electrically connects the tubular electrodes with each other; the insulating member and the insulated holder surround a conductive portion including a connecting portion between the conductive connection plate and the tubular electrodes in collaboration with the insulating holder and electrically insulates the connecting portion from the other portions; and the insulated holder, the insulating member, the conductive connection plate and the tubular electrodes are substantially closely arranged so as to make no gaps around the tubular electrodes in the load header.
