  • Patent number: 8092762
    Abstract: The present invention provides for an interface mechanism in a bio-separation instrument that makes interface connections to a multi-channel cartridge. The interface mechanism precisely positions the cartridge in relation to the support elements in the instrument (e.g., high-voltage, gas pressure, incident radiation and detector), and makes automated, reliable and secured alignments and connections between various components in the cartridge and the support elements in the supporting instrument. The interface mechanism comprises pneumatically or electromechanically driven actuators for engaging support elements in the instrument to components on the cartridge. After the cartridge has been securely received by the interface mechanism, the connection sequence is initiated. The interface provides separate high voltage and optical connections for each separation channel in the cartridge, thus providing channel-to-channel isolation from cross talk both electrically and optically.
