Patent ID: 7258776

Claim:
A system comprising an injection device and a capillary electophoresis device comprising capillaries, wherein the injection device comprises: a header; and a plurality of capillary injectors supported by the header, each capillary injector comprising a distal injection end that extends away from the header and comprises an electrode and a capillary tube; wherein the header maintains the plurality of distal injection ends in an array including a plurality of spaced-apart sets of distal injection ends, within each set of distal injection ends, the plurality of distal injection ends are spaced from one or more adjacent distal injection ends by a first distance, and between each of the plurality of spaced-apart sets of distal injection ends, the sets are spaced-apart from one another by a second distance that is different than the first distance, and the capillary injectors are respectively connected to the capillaries of the capillary electrophoresis device.
