1. A capillary electrophoresis system comprising:
- a base;
a plurality of wells disposed on the base;
an arm assembly mounted to the base and movable in three dimensions;
a detector docking station mounted to the base; and
a detector module comprising a capillary extending from an inlet end to an outlet end, a pair of electrodes extending adjacent the capillary inlet end and the capillary outlet end, and a detector aligned with a portion of the capillary, the arm assembly operative to move the detector module from the detector docking station to a working position with the capillary inlet end and an associated electrode disposed in a selected well and the capillary outlet end and an associated electrode disposed in a corresponding selected well.

Abstract
The invention is directed to a high throughput capillary electrophoresis (CE) system, which comprises multiple mobile CE detector modules that are transportable by a programmable fluid-handling arm assembly to fixed samples in microtiter plate wells for analysis. The CE system of the invention is capable of simultaneously automating sample preparation and multiple CE analysis of the sample in a continuous timely process. The CE detector modules of the invention may be equipped with any suitable detection method, such as an ultraviolet (UV) absorbance or a laser-induced fluorescence (LIF) detector.
