Abstract:
A gas chromatography system comprising a sample introduction device, an oven coupled to the sample introduction device and a detector coupled to the oven is disclosed. In certain examples, the oven may be configured to receive a chromatography column in a space in the oven. In some examples, the oven may be constructed and arranged to provide a substantially constant temperature to the space during an analysis stage of the gas chromatography system.

Abstract:
A document feed apparatus is provided which feeds document sheets from a stack of sheets seriatum to a position remote from the stack. Two motor driven feed belts are pivotally mounted to contact or not contact a top sheet of the stack. The belts are driven by separate motors which are activated or deactivated depending upon the top sheet position.

Abstract:
A method and apparatus for incubating a liquid reagent with target spots on a microarray substrate. A deformable cover is placed over the surface of the microarray substrate having the target spots with the liquid reagent between the microarray substrate and the deformable cover, and a device is used to apply a force to the deformable cover.
