ABSTRACT:
An interface is provided for use with a multiple sample acquisition device and a capillary electrophoresis separation device. The interface includes a body member having a base and an upstanding wall defining a generally hollow interior well. The upstanding wall includes an inlet passageway and an outlet passageway. An inlet guide member has an axially extending guide passageway disposed coaxially with the inlet passageway. An outlet guide member has an axially extending guide passageway disposed coaxially with the outlet passageway. An inlet capillary tube has an outer diameter sized for being received by the axially extending passageway of the inlet guide member, and a fluid passageway through which analyte can flow. The inlet capillary tube also includes a first end disposed exteriorly of the well and a second end disposed within the well. An outlet capillary tube has an outer diameter sized for being received in the axially extending guide passageway of the outlet guide member, and a fluid passageway through which analyte can flow. The outlet capillary tube also includes a first end disposed within the well and a second end disposed exteriorly of the well.
