Abstract
A micro-gas chromatograph column is formed by texturing a channel into a plurality of green-sheet layers, which are then sintered together to form a substantially monolithic structure. A thick-film paste may be added to the channel textured in the green-sheet layers to provide a porous plug sintered in the micro-gas chromatograph column in the substantially monolithic. A thermal conductivity detector is formed in the substantially monolithic structure by depositing a conductive thick-film paste on the surface of one of the green-sheet layers to define a resistor in an exit channel of the micro-gas chromatograph column.
