摘要： A carbon nanostructured micro-fabricated gas chromatography column which is particularly well-suited to the surface well-site and/or the downhole analysis of natural gas in oilfield or gasfield applications (but which may also be used in non-oilfield or non-gasfield situations) is described. This micro-fabricated column integrates a micro-structured substrate such as a silicon substrate with carbon nanotubes as an active nanostructured material in a micro-channel. Benefits of the present invention include enhanced separation of alkanes and isomers, particularly below hexane (i.e., below C6), as well as the separation of carbon dioxide, hydrogen sulfide, and water and other substances present in natural gas. The chromatography column of the present invention is in one embodiment a part of an entire gas chromatograph system that in its simplest form also comprises an injector and a detector. Preferably the injector, separation column, and detector are all micro-fabricated on a substrate.

摘要： A micro-valve (10) adapted for integration with a micro-fluidic device such as a micro-injector of a chromatograph, the micro-valve having a first substrate (12), a second substrate (14) having microconduits (36,38) and a seating surface (30), and an actuation membrane (16) positioned between the first substrate (12) and the second substrate (14) for opening or closing a fluid path (48) of the micro-valve (10) under a force applied by a mechanism such as a pneumatic or piezoelectric device, wherein said actuation membrane (16) is constructed from a poly(aryl ether ketone).
