  • Publication number: 20110209531
    Abstract: Embodiments in accordance with the present invention relate to packed-column nano-liquid chromatography (nano-LC) systems integrated on-chip, and methods for producing and using same. The microfabricated chip includes a column, flits/filters, an injector, and a detector, fabricated in a process compatible with those conventionally utilized to form integrated circuits. The column can be packed with supports for various different stationary phases to allow performance of different forms of nano-LC, including but not limited to reversed-phase, normal-phase, adsorption, size-exclusion, affinity, and ion chromatography. A cross-channel injector injects a nanolitre/picolitre-volume sample plug at the column inlet. An electrochemical/conductivity sensor integrated at the column outlet measures separation signals.

  • Publication number: 20110155871
    Abstract: A mounting apparatus includes a drive bracket assembly, a back panel, and a securing member. The back panel is mounted to the drive bracket assembly along a first direction. The securing member is slidably mounted on the drive bracket assembly. The securing member secures the back panel to the drive bracket assembly to prevent the back panel moving along the first direction. The securing member is capable of sliding along a second direction that is generally perpendicular to the first direction to a position, so the back panel is capable of moving along the first direction.
