MICROMINIATURE GAS CHROMATOGRAPH COLUMN

摘要

This invention relates to the field of miniaturing gas chromatograph instruments using microfabrication technologies. In particular, the inventio n provides a gas chromatograph column, which column comprises at least two lid layers and a channel layer, wherein each of said layers comprises a compact material suitable for gas chromatograph, said channel layer comprises microfabricated channels on both sides, said microfabricated channels and a side of said lid layers form at least two capillaries, said at least two capillaries are connected to each other through a hole in said channel layer to form an integrated capillary, said integrated capillary is connected to outside atmosphere on both ends via holes on two outmost lid layers to serve as an inlet and an outlet.
