Abstract:
A method for making a multilayered micro-gas chromatograph device, said method comprising the steps of:texturing a plurality of green-sheet layers in a predetermined pattern, said green-sheet layers including particles selected from the group consisting of ceramic particles, glass particles, and glass-ceramic particles, said predetermined pattern defining a micro-gas chromatograph column; applying a first thick-film paste to at least a first predetermined portion of said predetermined pattern in said green-sheet layers; and sintering said green-sheet layers together at a predetermined temperature for a predetermined amount of time to form a substantially monolithic structure, said substantially monolithic structure having said micro-gas chromatograph column defined therein and a porous plug disposed in said micro-gas chromatograph column, wherein at least part of said porous plug is defined by said first predetermined portion.
