<p>Disclosed herein are a multi-layer chip for gas chromatography and a method of fabricating the multi-layer chip. The multi-layer chip is fabricated by: forming fine channels at the same positions of a plurality of substrates using only a single photo mask and an alignment key; and stacking the substrates. That is, the multi-layer chip can be fabricated by a simple method, and the total length of the fine channels can be increase without a limit by stacking more substrates. In addition, layers of the substrates can be coated with different stationary phases, and a temperature control device can be attached to heat transfer contact portions of the multi-layer chip for controlling the temperature of the multi-layer chip rapidly and precisely. Therefore, the multi-layer chip may be useful for high-separability gas chromatography to separate and analyze an infinitesimal amount of a sample.</p> |
