Abstract
A hydrodynamic injector for substantially concurrently loading fluid samples to be analyzed into multiple capillary tubes of a capillary electrophoresis system. The injector includes an enclosure defining a pressure chamber for holding multiple receptacles, each containing a fluid sample, and apertures in the enclosure for passing capillary tubes into a position inside the pressure chamber and in fluid communication with the samples in respective receptacles. Electrodes on the enclosure extend into the pressure chamber for reception in the receptacles. The pressure chamber is pressurized with gas to substantially concurrently force the fluid samples from respective receptacles into the capillary tubes in preparation for a capillary electrophoresis operation.
